Yes, I found 3 or 4 of them last year (I always buy all Halves and Big Dollars a bank has). I don't check dates anymore so I may have found some more this year but don't know. I primarily look for the 40% silver ones. I have found [4] CRHing in the past year and a half and occasionally silver dollars - found [2] 1921 Morgans last year!
I picked up 21 Ikes today and when I saw the roll of 20, there was a silver edge. Sweet...I thought. Turned out to be a '72 that looked like it was chromed. Disappointing.
