VICK: just putting a coin in a household dryer won't simulate a " dryer coin
". These things are usually generated in laundromats and industrial dryers, that continuously spin for hours, load after load, or the coin falls inside the machinery and stays there rolling around for weeks or months before the repair guy pulls the machine apart and notices the poor thing in there.
Also watch your use of terminology. "Mule" is not a synonym for "error" or "weird coin", even though some eBay sellers treat it that way. A "mule" is a specific kind of mint error where two different dies from two different coins are used to strike a coin. This would be a "mule" if Lincoln were on one side and, say, the reverse of a dime was on the other.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
