I look for anything pre 64, buffalos, victories, silver war and westward journey nickels. I love that Canadian beaver. It's one of my favorite coins. I keep one on me from my birth year in a capsule.
Look for 1950 D (key nickel), Hardest to find nickel of all. Also 1982 - 83 each could bring up to 10.00. Stay away from 1964. You will find a ton of them, most struck of all nickels. nobody saves them.
You need to march down to that bank and raise hell over that penny in the nickel roll! Let them know that you have video proof and you are kind of a big deal on RU-vid!
