I have boxes of antique China from England etched in 18karat gold that i would like to sell. Would this be a place i could take it?

Absolutely. They can sell them for you

According to E bay and Replacements it IS. But I'd rather take them somewhere then sell my soul to mail it. But thanks

Yes and no - check it out on eBay first - or a site called "replacements" - just to see if it's worth what you think it t is - probably is NOT
