Neat coin, Colin!
These 12-sided coins really stand out. They were minted in nickel-brass, and some coins have toned beautifully over the years, giving them a very attractive look. Approximate catalog values:
worn: less than $1 US dollar approximate catalog value
average circulated: less than $1
well preserved all dates: $1
fully uncirculated before 1961: $10
fully uncirculated after 1960: $2
coins dated 1954, 1958 and 1960 catalog at $1 avg. circulated
1964 is a common date. Coins of this year, and most other years, are worth less than one US dollar when circulated. However, if they are in beautiful shape such as the one in our picture, a collector might pay one or two dollars to add it to his or her collection.
The 1953 date has the words 'BRITT: OMN' in the obverse description. Coins dated 1953 catalog at $1 when average circulated and $7 when fully uncirculated.
If you have a shiny coin in a holder, odds are good that it's uncirculated. A raw (unholdered) coin that has been in a pile with others for thirty years will never be uncirculated.
