Yes, perfect example. That dime/nail "error". I'm saying on way! That had to have be intentionally made. Plus, how did it got out?
A collection is "a group of interesting or beautiful objects brought together in order to show or study them or as a hobby." Merriam-Webster I see a "group," two or more error coins in your collection, which you have showed to us here on CoinTalk, so, yes, you have become an error coin collector. The 1961-D cents are very nice error coins.
Very nice pieces. 1935 is a great color. Goes to show that sometimes RD is not always the best than a beauty RB
Hey that's a good name for it "Peekaboo Lincoln" Considering I already named one of these the headbutting Lincoln, it's fitting to name the other one too.
It wasn't planned, it just turned out to be the ones that I have accumulated. As I was scrolling through auctions, some errors caught my eye. There were others that I liked but didn't win. I liked a few of the errors where the coin was struck on the wrong planchet. One was the following from a recent GTG thread. It was more than a bit out of my price range, but I can see picking up a nickel on cent (which will be way more affordable). https://www.cointalk.com/threads/guess-the-grade-my-dream-coin-w-poll-now.343456/ Usually I've noticed with errors that the more unique/uncommon, the more valuable. The NGC graded 1961-D Double Struck is the one that cost me the most. Maybe I should take it to the store and see if they'll accept it as two cents? I completely agree. There are tons of eye appealing RB and BN coins out there.
If you want a very generic price guide for errors, check the latest issue of Mint Error News. Naturally there are lots of refinements - an off-center showing the date is worth more than a generic off-center not showing the date. But it gives a rough idea.
