My father, who has passed away, left coffee cans filled with coins. I must have a dozen all filled with coins. He believe paper money would one day be worthless. He started saving the coins in the 1950’s. And yes I have one coffee can filled with silver dollars, half dollars, dimes and quarters.
Silver is currently around $24 per ounce. The individual coins may be worth more as a collector coin, though...................
You might have some valuable coins in those cans. Should consider going through them and separating out the older ones.
Keep all silver coins from 1964 and older. They still have actual SILVER in them. The rest, spend on bubblegum. ;)
Pennies, even really old ones, have little to no value.
