1987 Proof US Constitutional Coin Set $5 Gold and $1 Silver Two coin set complete with US Mint packaging and COA. They were minted to commemorate the bicentennial of the US Constitution. Many of the coins in these sets were cracked out. Who knows how many complete sets exist today? The pictures speak for themselves. Proof coins in hard plastic since the day they left the mint.  There isn’t any recent NGC price data on these coins except for melt values. So, we will start the auction at $605, the approximate 5/17 NGC combined melt value for both coins and let the market decide from there. Winning bidder will receive coin shipped insured with signature required. NGC Universal ID: FCU6
