Got 500 2020 lincoln shield cents all of them at least ms64 others have almost no flaws under magnification while some have spotting with almost no flaws.
Since a slabbed ms64 sells for probably around $20 I would say no, You would likely have more into it than it's worth. Plus since they are only a year old if somebody wants a high-grade one they can probably find it in change.
It would have to be a spectacular coin to be worth it from a financial point of view. I have some beautiful copper Wheat Ear Cents, graded at a 66 or higher. And how much did I pay for them last year? A whopping $5.00 a piece. Someone paid more than that for the grading fees and then add in the mailing and insurance costs. Just not worth it.
If you have 500 of them it seems like they would be very plentiful. That doesn't sound like something I would want to invest that much in. And, those don't appear to me to be high grade of any kind.
