While this is true...it's not 100% accurate. A 90% silver coin will never show copper on the rim...but a clad coin doesn't always show copper. So if you see copper the coin is clad for sure...if you don't, either is still possible. I don't know about dimes for certain, but I do know that for some denominations that examples have been found where old silver planchets were used in error on 1965 and later coins. It's extremely rare, but some do exist.
Agree, not seeing copper on the edge is never a "guarantee" that its silver. To the OP with your scale you really do not know anything, since your scale is too inaccurate. It could very well be a heavy clad coin. Get an accurate weight, or perform a SG test on it if you truly believe its silver. I do not think any 1968 dimes have ever been confirmed struck in silver, this is why we simply are skeptical. You are claiming to have a miraculous find, miraculous claims require miraculous proof. Personal opinions simply won't convince anyone. Chris
This is a business strike dime. It was struck in Philadelphia. It is not silver. It is copper nickle clad. Only proof coins in 1968 will have the S mint mark with the exception to the 1968 no S mint mark proof. The only coins minted in silver after 1964 were the Kennedy halves and they were 40% clad silvers and the silver coinage for business strikes ended 1970. I might suggest, since you are new to collecting, picking up a copy of Whitman Publishing's Red Book by Yeoman. Many consider it the authority of information on coins.
I once found a quarter from the 70's that I swear I thought was silver just because of the ring it made when dropped on a table, this was before I knew to check for the s mint mark so I just put it back in my change jar.
There are subtle color differences between silver dimes (They look whitish) and clad dimes (Look greyish). This coin has the color of a clad dime. Does that mean it's not silver? No, it just means that I really doubt it's silver. OP, if you want to send it to me along with a check for $50, I'll send it in to PCGS for you.
It could be silver if........it was a counterfeit and someone used silver to make it, but just from looking at the picture you can tell it's not silver because it just doesn't have that silver look to it. If he collects silver then he should know that the color is wrong. When I was younger and had my metal detector, you could even tell silver from clad as you dug it out of the ground and it was covered in dirt.
Will some body give me feedback on these quarters? This one really looks copper had a big v shaped dent in his head
You should really start a new thread Phil, but it looks like your quarter has spent some time in the elements. (Envirnomental damage)
