This is a very rare and tough set to put together in 69. The 1/2 oz has a small mintage of roughly 4100 coins. Of these 4100, some are small date while others are large date. That means there cannot be more than 4100 total sets. This also means there can only be so many small date and large date sets available. To have each of these graded 69 is HUGE. Always purchase authenticated, graded and encapsulated coins. Protect yourself - Protect your coins.
