This is the third part of a feature by Rita Laws exploring the growth in popularity of 5-ounce silver coins over the past four decades.
Once Panama paved the way for large silver coins, it was only a matter of time before a nation issued a 5-ounce silver coin. But in between, a bevy of issues approached but just fell short of that significant size.
1985: Close but no cigar
By the mid-1980s, big silver was all the rage on the world collecting stage. Several nations winked at the 5-ounce mark but none committed until 1986.
The Bahamas issued two large sterling silver $25 coins in 1985. The San Salvador Christopher Columbus commemorative coin weighed 3.5 ounces. The other, slightly larger at 3.8 ounces, had a twin flamingo design, a nod to the beloved Bahamian Flamingo $2 coin minted between 1966 and 1991.
Jamaica issued a number of 4-ounce .925 fine silver $25 coins between 1978 and 1985. The Falklands issued a £25 coin in 1985 celebrating self-sufficiency and weighing 150 grams or 4.82 troy ounces, according to its certificate of authenticity. So close!
Collectors looking for these coins at online auction sites such as eBay should know that these are often sold to this day as 5-ounce silver coins, when they clearly do not weigh that much.
When buying any large silver coin, especially those minted before 1986, it is a good idea to check a reference book for the exact weight or ask the seller if there is a certificate of authenticity listing the official weight.
Online buyers should also be careful about purchasing 5-ounce medallic coinage and fantasy coins marketed as legal tender bullion. A few of these that appeared in 1985 and 1986 include the Liechtenstein 10-taler piece, the Austrian 5-unze piece, the Netherlands 5-daalder piece, and the Chinese Panda silver 5-ounce medal.
All of these are listed in the sixth edition of Unusual World Coins, a medallic coinage and fantasy coin reference book by Colin R. Bruce.
