2015-W American Eagle 1/10oz Proof Gold Coin In original boxes with papers. Unlike the Bullion grade coins these proofs carry the "W" mint mark from the U.S. Mint at West Point and feature sharp frosted designs on mirror-like backgrounds. A very collectible coin and from what I can tell are hard to find in Australia. I’ve not been able to find in Australia but online in USA retail about $350 AUD. Obviously not including international postage. selling this one for $350 posted Aus Wide.
