I’ve done some research and I know that a weak strike can produce a coin that looks like these. And I know that a person who is bored can spend time grinding and buffing a coin to get this same effect. I don’t have weights but I do have measurements. The penny is 17.22mm in diameter and 1.01mm thick. The nickel is 20.96mm in diameter and 1.25mm thick. And the quarter is 21.68mm in diameter and 1.37mm thick. The penny and quarter are quite a bit smaller than should be. The nickel however is close enough that makes me wonder if it could be a weak strike on a thin planchet. Any help is greatly appreciated and thank you in advance.
If you put coins in a rock tumbler long enough you will get that effect. Those are not Mint Errors of any kind. - Mr. Ed Specializing in collecting Mint Errors since 1985
Ed, ...of course he is. I was going to say they all appear to be dryer damaged. All are worn smooth and you can see the heat damage, too...imo...Spark
Just very heavily worn, not weak strikes, not grease filled and not attacked with a grinder, Damage to "dryer coins" has NOTHING to do with the heat of the dryer (at least not a clothes dryer) The metal in the coins isn't going to soften or distort from heat until you are in the 1,500 - 2,000 degree F range. Your clothes would be toast long before that point.
To ad one piece of useful information, when you do find a weak die strike the upturned rims will still be present
...I thought coins were susceptible to the heat from dryers, didn’t know they were that durable. Thanks for the correction ...Spark
