I have a 1969 s mint double die Lincoln cent in really good condition. I know this coin is extremely rare and can be quite valuable. My question is how valuable is mine?

That coin is not worth more than one cent.

The ONLY PEOPLE who can give you a straight answer is a coin expert like those at Rotalty Coin , calling is not going to cut it, they must see the coin .

I have a 1938 nickle 1940.52 and 63Dd nickel all in decent condition any one have an idea or know someone that is looking I have looked them up and THAY are 4 of the most looked for

im sorry we are not buyers or sellers of that particular coin

My suggestion is to go to coin collectors to 👀 who can give a better offer.
