Welcome to Numista. Please no not confuse Numista rarity index as an indication of overall rarity in the marketplace. It is only an indicator of how many Numista members claim to possess a particular item. Having said that, assume bullion value is what you could expect to get for a bullion coin unless you can find someone willing to pay more than that for whatever their reason for paying a premium over bullion value. Todays value 18.26 USD.
