Just wondering, any particular shield varieties or known errors I should look for on cents minted from 2010-present? I search boxes and have opened a lot lately that have been mostly 2018 D. Been getting to the point where if both enders are shields, appear new, and the roll weighs 125.8 grams or so, I just dump em.
No, I don't think there is anything valuable in 1 cent coins produced 2010 to present. I have been saving some 2012 and 2013 uncirculated shield cents, but, since they're not key dates, I just spent them when I wanted to pay for something with exact change.
Oh, I almost forgot, there IS the 2017 "P" cent, which is interesting because Philadelphia coins are typically missing the mint mark, but, last year- for the 225th anniversary of the US mint, the mint decided to strike the Philadelphia cents WITH mint marks. Though unusual, I doubt they have any extra value unless you have a lot of them. I saved a couple when I got them in change, but, since I live in the Bay Area, I don't see many Philadelphia coins-mostly Denver.
Yeah, I saved a few rolls of the 2017 P's. I'm north of you, hard to find anything without a D on it!
There's been a host of DDO's and DDR's, but because of the single squeeze die making process, they are very minor and don't contain a massive premium. Outside of that, just keep an eye out for CUD's, MAD's, Off-center strikes, die clashes, broadstirkes, and rotated dies. Also, some coins miss some or all of the copper plating. In the same breath, don't expect to find much, maybe a few die chips if you're lucky.
