According to my research and confirmed by Dick Johnson, only 58 of the large gold medals were struck. These medals were not numbered consecutively. Bob speculates that some may have been melted, but considering the rarity of the medal I doubt that many were melted as the issue price was $850.
The medal contains almost seven ounces of gold at .900 fine. A recent eBay sale of this medal brought $8,250 (9/12/06). Every time I have seen this medal for sale it was for more than the bullion price.
