I recently searched some cents and nickels; I found some older nickels, some wheats, and some Canadian cents; also I searched a friend's coin jar, and found some old nickels, some wheat cents, and some Canadian cents. I also save any possible error coins, basically any coin that catches my eye that looks off.
Got $300 in dimes (including a box of dimes), and some nickels and cents. I will look through them once I make some space in my bedroom. Also got a roll of cents at the grocery store, brand new 2020-D enders; I will sell the roll on eBay.
