Rare Original – Guaranteed Authentic – U. Navy Seal Challenge / Membership Coin. I believe this coin dates to the 1970’s to early 80’s. Its construction is reminiscent of the early Army SFG coins of the 1970’s. There are known copies of this coin with smooth edges and each are obviously newly constructed. It is named/engraved on the lower banner portion. This is truly a rare coin – not like the modern shiny coins made en masse today… Please see our other listings, and check back often as we typically list 30-50 high-end estate items each week with No Reserve!
