These gold ducats from Hungary are beautiful coins. The coins in this series, 1731 to 1740, contain 0.111 troy ounces of gold, giving them a base value (BV) of $128 US dollars at today's gold market.
Figure the current BV by multiplying the current gold 'spot' value by 0.111. For instance, if gold were at $1300 US dollars per troy ounce, the BV of this ducat would be 0.111 x 1300 = $144.
Collectors will pay more than BV when a ducat is in good numismatic (coin collector) condition. Here are rough values:
average circulated: BV + $25 US dollars
well preserved: BV + $100
fully uncirculated: BV + $350
Unfortunately, requester Moe's coin is a fake, worth zero. The second picture shows Moe's coin and it is clearly different than the genuine coin shown in our main picture at upper left.
