Hello,
I recently came upon this anomaly in a lot of dateless buffalos.
The Obverse or Reverse

The Reverse or Obverse

Two shots of the suspicious edge


Diameter : 21 mm
Thickness: 2.1
Weight: 6.5 g
Coin Alignment
I had restored the dates before taking the pics. I am almost 99% sure that this is some joke. I would not think anyone would try to pass this off as genuine especially after seeing the dates. However , I put this out there for you aged and/or wise folks to commiserate upon . The edge looks a little suspicious as though it was welded or pasted together , the product I am saying , of some one with too much time on their hands. Of course I probably have too much time on my hands to even bring this up for consideration. But, I leave it with you.
