Nice coin, Paul. The florins from King Edward VII are especially valuable. I am not sure why this is so. Maybe it is the image of Britannia on the reverse. Nevertheless, here are some catalog values for *common date* coins in this series:
worn: $15 US dollars
average circulated: $40
well preserved: $120
fully uncirculated: $400
Now there is *good dates* as well, and you've got it, Paul! A 1905 florin is worth $200 in average circulated condition.
These are catalog values. Be sure you understand what this means by checking our Terminology page.
Since you indicate 'little or no wear' in your questionnaire, the catalog value for your particular coin, Paul, probably approaches $500. Not bad. But beware of damage on your coin. The picture shows a close up of the King's beard, and you can see severe scratches going across the field between the image and the lettering. Damage such as this renders the coin almost valueless to experienced collectors. Even with a catalog value of $500, if your coins is scratched, cleaned, or otherwise damaged like the one in the picture, the most you could probably get would be $20 to $50. The only way to get more would be to sluff it off on an unsuspecting, inexperienced collector which, sad to say, many coin dealers are more than willing to do.
We lifted the coin image on our page from an eBay auction. Normally we are careful to request copyright release on all our coin images. But not this one. The dealer is obviously selling a scratched, damaged coin, and he neglects to mention this fact in his description. He even has the nerve to call his coin 'high grade.'
Coin buying is strictly a 'let the buyer beware' proposition.
