I bought a coin collection last year small one and it had several coins that are labeled replica's So I bought another coin, one just like one I had on ebay and weighed them and they are like 7 grams off of each other. So here is the question I had thought about drilling one out and taking the slag or file ins or what ever and doing a silver test . Because I do not want to ruin the good looks of the coin by dropping acid on it. Any other idea's ? I figured it could be a necklase LOL THANKS JON
