You're raising funds for a CNC machine to make plywood boxes for nickels? < Not sure if serious >
Worse than that I am offering the idea. hoping someone would take over a CEO as my mechanical skills even with a CNC are bad. I was trying to think of some business other than lending or mining that would work. Everybody likes silver and gold, but the real untapped coins are pennies before 1982 and nickels. In 1970 you could go to Las Vegas and if you went to some casinos, they use real silver dollars. We are in that era for pennies and nickels now.
