I found a 196? Roosevelt dime with a complete collar break off the planchette. There is also a planchette chip where the last number in the date would be. I am new to the hobby so any advice is much appreciated
If it is silver then the date would be 1960-1964. If it is of clad composition then the date would be from 1965-1969. For the dates 1968 and 1969 a letter D may be above the date if the coin was minted in Denver.
Just for education is the damage the collar broken off (not from the mint). Or just the poor condition the coin is in ?
I think you mean the Missing Rim.. That was worn away due to circulation. Nothing to do with a Mint Error.
