I had thoughts of using the worst Zincolns (after tumbling) and doing end table tops or wooden serving platters.............get some practice on smaller areas first, then look at doing larger areas.
I was researching the history of a treasure hunting club in Oklahoma, trying to help someone here on TN with a question.
I came across this note describing a club meeting in 1970:
"March - Wilbur Heuszel gave a presentation of all the coins he'd found. He had 46 cans of pennies alone."
I remember KvonM writing about a th'er who had found 1,000,000 pennies (he kept them in a washtub). Karl said that was by no means the first person he knew who had done that.
