Although this coin is worn it still looks odd as to the way it has worn equally on both sides. Measurements seem to be correct, however very weak around rim on both sides. Hopefully the picture helps.
Any insight would be helpful.

I would say a dryer coin. Look in the archives here and CCF forums.

Here's a past thread on CCF, but there are many more threads and some look just like yours:

Could also be a coin that was in the ground for awhile.
Whatever caused it, it is only worth face value.

Thanks
