These old Queen Victoria six pence catalog as follows:
worn: $10 US dollars approximate catalog value
average circulated: $30
well preserved: $50
fully uncirculated: $125
Each coin contains 0.090 troy ounces of silver, so the value will never go below that much silver. The piece in the picture is almost uncirculated (it may be fully uncirculated, but it is difficult to tell from the picture).
These are catalog values and they apply to all coins in this series which runs form 1893 to 1901. To understand what 'catalog value' means, go to our Important Terminology page.
