925 Silver is a silver-based alloy that if done right is 925 parts per 1000 silver. Theoretically same as sterling silver

Gold coins can be pure gold, or not. When not pure, they are alloyed with a hardener. What counts in gold coins is the fine gold content. Thus, for example, a one-ounce troy pure gold coin has the same fine gold content of a 22K gold coin, but because of the hardened, the 22K gold coin is a little heavier.

Junk silver is a term used for 1964 and older US fractional coinage made of 90% silver. https://portlandgoldbuyers.com/silver-coins/

First look for the hallmark "925" or "Sterling". If you don't find that, you may have to do some testing.

Gold nuggets, flakes and dust are different manifestations of placer gold, which is gold that was in a river or stream. Basically is the same gold material in different particle size. https://portlandgoldbuyers.com/gold-raw-gold/

Call around, ask for prices by the gram, compare answers and attitudes.

You can test gold electronically, by Xref, chemically, by density, ultrasound, displacement, fire assay, etc. All are good. It just depends on the situation. https://portlandgoldbuyers.com/gold-testing-electronic/

The quick answer is "NO". Gold coinage is bullion with monetary nominal monetary face value. Thus most older gold coins are worth their gold content, which is the job they were made for. There are of course coins of numismatic value beyond the gold content. But that is another subject.

Silver plated items are worth the recycling value their main mass is. That is basically copper recycling value. Not silver value. So they are worth very little.

US coinage was 90% silver until 1964 for half, quarter and dimes. Until 1934 for Dollar coins. https://portlandgoldbuyers.com/silver-coins/

The value of silver fractionals as per the question is spot market. At selling there will be a dealer discount. Do this equation: weight of the coins in grams multiplied by 0.90 multiplied by spot market in grams. https://portlandgoldbuyers.com/silver-coins/

In terms of silver content, the silver ounce is worth more. However, by the gram, the silver dollar is worth more by the gram because it goes for close to the silver ounce, but has less silver. https://portlandgoldbuyers.com/silver-coins/

The silver dollars have a collectible, cool factor, so although they don't go for much, they are basically worth more in the USA because they are older, classic coins. https://portlandgoldbuyers.com/what-is-a-silver-dollar-value-of-a-silver-dollar/

NO. They are 90% silver. https://portlandgoldbuyers.com/what-is-a-silver-dollar-value-of-a-silver-dollar/

By the spot market, it is their weight of 26.7 grams x 0.9 x spot market in grams. However, at the retail level silver dollars go for more depending on several collectible factors. https://portlandgoldbuyers.com/what-is-a-silver-dollar-value-of-a-silver-dollar/

90% of the mass is silver which is 24 grams if the coins has not lost mass. https://portlandgoldbuyers.com/what-is-a-silver-dollar-value-of-a-silver-dollar/

Gold nuggets are not uniform. Consider them to be a little better than 18K. So multiply their weight by 0.75 to get an approximation of gold content ballpark. https://portlandgoldbuyers.com/gold-raw-gold/

NO. Gold nuggets are from nature, not from the refinery. https://portlandgoldbuyers.com/gold-raw-gold/

YES and NO It is not that appraisals are high. It is that people misunderstand them. They are the insurable value, not the liquidation value. Read the article in the link below to know the details. This is not a single paragraph answer. https://portlandgoldbuyers.com/gold-raw-gold/

Means the same as 22 Karat gold. Read the article below. https://portlandgoldbuyers.com/gold-22k-gold-gold-916-920/

I do welcome walk-ins. However, as said above, I by far prefer appointments. Here are the reasons. It helps me do a smoother job 1- Some transactions require me to do some homework in advance. If you have diamonds, for example, it is better if I get any existing paperwork first. If no paperwork is available, then I need to inspect the piece very well 2- I may be with another customer at the time someone arrives. Thus, the person without the appointment has to wait, or come back 3- I can better plan appointments when I know what is going be happening during the day. 4- I don't like hurrying transactions. Maybe a transaction will take longer than the person without the appointment expects. Thus, to complete the transaction I will have to act hurriedly. I try to avoid doing that

Anna, I do buy e-scrap but I have a lot of qualifiers. What is exactly what you have? If it is something I can work with, then I can make you an offer. Email me some pictures and descriptions. E-scrap is a very broad term.

Jonathan, I deal exclusively with precious metals. So I don't deal with pennies. What other things do you have? Oscar (Owner of Portland Gold Buyers, LLC)

I pay depending on the karat and the weight in grams. Call me the day you want to sell with that info. 971-222-3435

Gold nuggets are never pure. Most gold nuggets are for the most part nuggets are just over 75% pure fine gold. Pure gold only happens after refining.

Depending on what you have, and market conditions, for gold bullion, I pay up to spot market.

Hi, This is Oscar. I am the owner of Portland Gold Buyers, LLC. Here is the complete answer about the ID situation. ID Needed: Valid ID is needed for selling anything that is personal property. So if it is jewelry, silver flatware, etc, an ID is needed. ID Not Needed: No ID is needed for selling any silver bullion in any form. So if you are selling silver coins, bars, etc. I don't need an ID. Hopefully this answers your question.

Lars, I buy anything made out of precious metal. So if something is made out of gold, silver, platinum or palladium, I will make an offer. Oscar

Probably around $400

Means same as 10 Karat gold. Learn more at https://portlandgoldbuyers.com/gold-10k-gold-gold-416/

Generally speaking, the hallmark stamp indicating fineness is accurate. You can basically count on it for example wedding bands. Other items, because of the way they are built, actually have less than the stamp, but for good reason and justified, and fair. However, "stamping is for free" so dishonest jewelers abuse the stamp.

Look for the stamp. That is a good place to start.

Start by looking for the stamp. You may have to do some testing if it looks inconclusive. Learn more at https://portlandgoldbuyers.com/gold-testing-nitric-acid/

Pawn shops different than gold buyers, but they overlap. Usually a dedicated gold buyer such as Portland Gold Buyers, LLC pays more. Typically the pawn shop offers more based on the math of doing a pawn. Shop around. That is the best way to find a good deal. https://portlandgoldbuyers.com/jewelry-pawn/

The intrinsic value of sterling flatware, holloware, and similar utensils is the recycling value of the silver. I buy silver flatware and similar items by the gram. Call me for an offer. I had to melt wonderful silver objects because they where obsolete and nobody would buy them. Here is more info https://portlandgoldbuyers.com/sterling-silver-flatware/

Gold filled is, for the most part, a heavier coat of gold over a copper-based core metal. So gold over brass for the most part.

Gold plated is a typically thinner coat of gold over a ferrous, magnetic core. Only the very surface is gold.

Coin silver is a silver-based alloy that is 90% silver. This is the same standard as the American, Spanish and Latin American coins. Thus,"coin silver".

In principle, Sterling is the same as 925. The Sterling standard is a silver alloy of 925 parts per 1000.

Sterling silver is a silver-based alloy in which 925 parts out of 1000 are silver.

In Sterling silver, theoretically, there are 925 parts of silver out of 1000 parts. So multiply by 0.925 to get the fine silver mass.

They are different coins produced by the US Mint at different eras. - The American Eagle is 91.6% (percent) gold and has a fine gold content of 31.103 gram, which is 1ozt (one ounce troy). Minting started in 1986 - The Double Eagle is 90% (percent) gold and has a fine gold content of 30.093 grams, which is 0.97ozt (once troy). Minting ended in 1933

The One Ounce Troy (1ozt) Krugerrand, same as the American Eagle, gold coins have a fine gold content of 1ozt of gold. Above that, there is an additional mass of hardener. The hardener dissolves the fineness to 22K, without altering the fine gold content.

A Krugerrand is 91.6% pure, which measured in karat fineness is 22K Learn more at https://portlandgoldbuyers.com/gold-coin-krugerrand/

NO. There are 90%, 91.6% and 99.9% and 99.99% fine gold coins. What matters is the amount of fine gold content, not the fineness.

There are 22 parts out of 24 gold. Multiply the weight by 0.916 to get the amount of fine gold.

There are 18 parts out of 24 gold. Multiply the weight by 0.75 to get the amount of fine gold.

There are 14 parts out of 24 gold. Multiply the weight by 0.583 to get the amount of fine gold.

There are 10 parts out of 24 gold. Multiply the weight by 0.417 to get the amount of fine gold.

White gold is a gold alloy in which the yellowness has been "washed out" by additives such as palladium, nickel, and other elements. Other than the color, it is the same the other gold alloys. Learn more: https://portlandgoldbuyers.com/white-gold/

Dental gold is a medical product. Not jewelry. Thus dental gold alloys vary based on the medical need. If the dental alloy is yellow, most likely is going to be equivalent to 14K. It is hard to test dental gold accurately because of the way it is alloyed affects the gold testing methods. So electronic testing and chemical testings show up higher. It may or may not be higher.

Generally speaking, dental gold is very close 14K. That is what is more easy to prove. There are higher karat applications, but they are hard to test accurately, plus they are not the majority. Learn more at https://portlandgoldbuyers.com/?s=dental+gold

I am the owner of Portland Gold Buyers, LLC. Yes. I buy silver flatware. Make sure it stamped Sterling or 925. Make appointment if you want to do it. Prices are adjusted as per the market.

I am the owner. I buy gold and silver coins only. Not regular, base metal coins.

I am not specialized in numismatics. However, I have seen a few error coins, and I contact with very competent numismatic dealers. Most error coins are not worth more than a regular coin. However, you can easily get over a dollar for a penny, which proportionately is 100 times more, but in absolute terms, it is just one dollar.
