I see no doubling. Remember that Doubling related to a true Doubled Die would fall under the Variety category.. not the Mint Error category. Here is some great information - Variety vs. Mint Error | NGC (ngccoin.com)
Sorry, but I can't see why many members look so hard for minor things and then try to convince others they have a certain variety or error. It's a dime, worth 10¢ to me, so unless your collect MD, DDD, worn die, coins, it has NAV. Just my opinion.
I haven't seen any others like it. Little errors are still errors. You may not want them but someone does and they are fun to find. Thanks
I said IF. Yours isn't, it is strike doubling. True hub doubling disappeared when the single squeeze hubbing method was introduced
I will keep it and look for another strike doubling in that area. I have yet to see anymore like it. Thanks.
