Edited ~ any discussion about the buy/sell/trade are not allowed within the regular post, and must be in the B/S/T sections.
Be careful with the offers of buying and selling, forum rules do not allow this. Doug will come to your house, kick down your door, sternly scold you and make you stand in the corner.
ok, if you are right, (good chance you are) sorry for wasting everyones time. right now i feal like an idiot not to see those and think, "hmm, whats up with that copper on the coin?" and relise its not silver. just one question, why did it end up being the same wheight as the silver coins? (spelling is unchecked)
It's possible someone had silver plated it which added some weight and makes the edge appear silver. Then where it chipped you see copper color coming through the rim which gets the most wear. Also, could depend on the accuracy of your scale with something so light as a dime. My scale which I use for weighing out soap making supplies (oils and lye) goes to two decimal places and is digital so it's quite accurate.
The problem with your theory is that the copper doesn't show on the rim, it would show on the edge. The only time I've seen copper on the rim is when the coin is ground down or otherwise damaged. Certainly not from just wear.
If you expect to sell that as a genuine Mint error 65 dime struck on a silver planchet, it won't sell unless it's slabbed by PCGS or NGC. I would take it to several dealers, whom you know and trust, for their assessment and if they believe it to be real, I would submit it to one of those two for slabbing. Just my ten cents.
One last quick question/comment: did you actually weigh the dime, or did you just balance it out against a known silver dime? This balancing (on a pop-sicle stick over a pencil) is good for gross fakes of larger coins, but here we are talking about a small weight difference. If you want to be absolutely certain, take it to a college chemistry department, and someone there would be happy to weigh it for you to the nearest ten-thousandth of a gram!
Do not feel like an idiot. You have not wasted anyone's time because they voluntarily participated. You are learning and some of the teachers could have handled themselves with more civility and understanding despite whatever may have occurred in the past at this site. Someone once made me feel foolish shortly after joining and I wrote a scathing reply. I do not plan on doing that again because it was a waste of my time. If someone thinks they are so smart that they must pick someone apart, they have issues. If you find coins interesting, just keep on coming back to the forum and ignore anyone who acts like a horse's rear.
