Roll Hunting And Minimum Grades For Varieties

I don't mind keeping low grade varieties. I'm concerned I'm going to waste a lot of time looking for varieties on coins where the "evidence" has worn off.

Thanks for your responses.

I'm not at the "looking for variety" stage yet. Chuck recommends sorting a lot of coins by date, then looking through several coins of the same year in succession (does he say "hundreds"?).

So I'm sorting right now. So later, let's say I go to look at 130 1937-D (oops) 1977-D cents...am I going to learn that many of them are too worn to notice if there is some sort of doubling or if there is an RPM? Or I won't be able to figure out which variety it might be on worn coins?

Maybe these details are still visible on average circulated coins, and I'm asking a stupid question.

for memorial cents just cull out damaged and corroded coins. Grade isn't a factor because nearly all memorial cents are still at least EF in grade by details, and once the corroded, bent, damaged, scraped coins are culled out, the rest are all searchable.

I don't keep anything in memorials after searching except BU coins. All wheats are kept, but I still don't search damaged coins.

i would keep even the culls "corroded, bent, damaged, scraped coins" of some varieties, a 1992 Close AM would still worth thousands of dollars even if it was corroded so bad Lincons face fell off.
