I got my F75 back from the shop and took her out last night for an hour to give it a test. It is working perfect, thanks to Felix, Daniel and the Fisher crew. These coins are not old because the park is not that old, the oldest was a 67 dime at 7". I found 2 nickles, I love finding nickels among the pull tabs, the F75 hit them all perfect. I don't think the little ring is even silver coated but it was fun. The F75 is a great machine.
