Elizabeth II gold 50 Dollars 2005, MS69 PCGS, AGW 1.0000 oz. This is an experimental issue struck with five "9's" indicating the coin's purity for one ounce of gold. While 600 coins were originally minted, 200 of them were melted down leaving only 400 coins that were released to the public. A beautiful and rare, bright-gold gem with flawless, prooflike surfaces and endless luster.
