It means that the number on the die got filled with grease and never appeared on that coin. Very common error with no added value except in extreme cases
@Rob336 FWIW, I don't think grease, alone, is capable of filling the die to make a digit or letter disappear. Just like concrete needs sand and gravel to harden properly, the grease needs dust and debris compacted with the grease to harden to an extent that will fill a letter or number. Chris
I'm no veteran on coin hunting for sure. But it does seem when your surching hundreds of coins you would find more.
Im pretty new to coin collecting, compared to 99% of you guys here. And pennies arent really my thing, but me and my son go thru some when he feels like being interested, so im sure we have stuff just dont know it yet. but a missing number? nope never seen one yet. And pocket change hunting is pretty fun. Star hunting notes comes a strong second, and believe it or not Walmart goes thru tons of bill and we have found alot of stars there.
Thanks for the walmart idea that's good for you with the star notes the only thing is they don't sell penny rolls for me LOL have a great day and and good luck I started doing it with my dad when I was a kid 2
A more thorough explanation from the Sullivan Numismatics site: 'Where do all these things come from so that they can be struck into the coins? Well, the mints are factories, with lots of equipment made up of thousands of parts, machines dripping grease, bolts, screws, and random debris, and so there are lots of things which could break off, come loose, or accidentally be fed into a press striking coins.' https://sullivannumismatics.com/information/articles/strike-through-error-coins
