Here is a Survivor coin I have had for 10+ years. The coin Is RAW and kept in it's coin sleeve.
I removed it using cotton gloves just for pictures.
I have taken several pictures under different types of light to give you the best prospective of this coin.
If I had to do it all over again I would join PCGS and submit this coin to them myself!
But It's gotta go!
Good day!
