2012 "Exchange Currency" Concept Barter Token, 63mm 4 Troy Oz Silver, Hologram, Winged Liberty Head Facing Right, Only 25 Minted

Each coin is struck on a single piece of solid silver. The center design is struck first, followed by the striking of the holographic border. The hologram applied to both sides of these coins is struck directly into the silver. No sticker, film, or coating is used. The surface is nothing but pure silver. Note that every coin will have some irregularities in the hologram area - such as ghosting of the numbers.
