In Your Opinion, What Year For Lincoln Cents Is The Best For Any Varieties?

Yep, them ebay sellers know all the tricks!

1966, and also the 1966. Sorry crazybo I couldn't resist harharhar.
Seriously though the only unopened rolls I buy are at shops, flea markets, and other collectors, in hand you can tell if any tampering has been done. Also many 1974 D bank rolls have 74 S coins mixed in them thanks to a unpopular mint director decades ago. If you can pop a 66+ 1974S out you got a dandy registry coin.
My vote is for the stepchild year 1974, several different variety mixed in.

I made a mistake early on (as in within the last year) of buying a supposed OBW half-roll of Buffalo nickels off ebay. When I received it, one crimped end was legit. The other...obviously opened and "re-crimped". Frayed fibers from the wrapper all over the place and too pliable to be original.

Any guesses as to what I found in it?

...That's right: nothing. All very circulated commons. I learned the lesson real quick.

They may have served a purpose, however, because I sent them to coin197 to hand out to YNs at the World's Fair of Money.

Myself I'd say the 1982 cents would certainly be in the running for varieties.

I agree that the 1982 series is interesting from a variety standpoint. My issue with them is that, as a rule, they are poorly-struck and unattractive coins, even the coppers. The early 60s are generally prettier coins, especially in EDS (but they worked dies to death then which may be why there are so many varieties.)

pick one but hunt anything when you need to eat I look for one never been discovered

From a doubled die standpoint, 1972 is the obvious choice. But, two more affordable rolls may be 2006 P and 2009 Formative Years.
RPMs will be 1956 - 60 D.
Clashes/Cuds will be 1983/84
Trail Dies - 1994 (the 90s in general, with the nicest ones coming from 94, 1994P-1DER-023T)
etc

Years ago I bought bunches of rolls. Years ago means I was getting 46-S cent rolls for under 20 bucks !
Original bank rolls were not a thing then. What got me going was tubed rolls with clear tape around the lids that had yellowed with age. Just about guaranteed to not have been cherried.
Don't get depressed if you get skunked on rolls. Ir will happen.
As many rpm's as 1960-d cents have , I was skunked by a mint sewn 1960-d bag . 5000 bright shinny non rpm's ! Other times half the roll are winners!
