First Box Lincoln Cents: Synopsis

But they are 40s, which I imagine are the most common.

Nice box for wheats. My last box had 2 wheats in the entire box.

If you aren't already, you should search for some of the errors/varieties.

Here's a few easy ones.
1988 and 1988D and look for any with the reverse of a 1989.
1992 and 1992D and look for the Close AM
1998, 1999, 2000 and look for the Wide AM

I also take each coin and flip them over north to south and make sure the reverse lines up with the obverse, but not much added value until you hit 90% rotated die or 3 o'clock.
If you find something odd/different post it, it might be something cool. I found my avatar coin in my first box and didn't know what I had. I thought it was just a damaged coin.
There are tons of other things you can look for as you learn. (I hope I'm not assuming incorrectly that you're new to this :P)

Good luck, Happy hunting.

Congrats on your first box.I started about a year ago, but mainly with 6-10 rolls at a time. Have fun!

For the copper it's about average and the wheats you are doing pretty good on them.
