It looks to me like it has been affected by the environment. Usually, coins that are missing the clad layer have a tendency to turn brown while in circulation similar to pennies. Here is an uncirculated half dollar that I found in a Mint bag. Chris
Thanks, Paul! Even after all these years, I'm still amazed at how lucky I was to find it in a Mint bag. Only two for this date/mm are known, and that was just sheer luck for me and the other guy who found his specimen. Just, think, if the reverse side had been facing up anywhere along the conveyor system, it might have been removed and destroyed because it would be so easy to spot it. Chris
My uncle lived in Ft Lauderdale. He had a collection of toasty brown dimes and quarters he found in parking lots and the courses while searching for golf balls. Can never understand what drives a guy to collect garbage bags full of golf balls in retirement. I guess it kept him out of trouble.
When my son was a toddler, I used to take him for walks through the local golf course to hunt for balls. I ended up with several hundred, and when I was living in South Ocean City, MD I had nothing better to do with them except practice driving them across the canal into the marshes. I figured that some developer might come along a couple of centuries from now and when he discovered the balls, he would think it used to be a golf course. Chris
