For silver content I made a small spreadsheet that might help. This is screenshot based on today's silver price.
‘71 - ‘78 on the Ike dollars is only for collectible coins (as in 40% silver proofs or uncirculated bought from the mint at a premium price). You will not find those in circulation unless some thief robbed a collector and doesn’t give a damn about getting full value vs. getting some money right now.
Thank you for that chart!
Based on the advice in this thread, I will probably just get a bank account at a bank with a coin machine...but I think I will first use your chart to weed out and keep some of the coins with decent silver content. That could be done relatively quickly. I have a cheapy sorting machine.
Coinstudy.com is a good starting point for coin values. Updated regularly.
I emptied our stash and found one bicentennial quarter, one BUFFALO nickel, a foreign coin, a wheat penny and one other coin I forgot what it was....
