Sadly this is impossible to answer without much more information. It sounds as if you might have a Victorian Diamond Jubilee medallion. This comes in two sizes and three different metals. Condition of the item plays an important part in determining value also.

V.R (for Victoria Regina - Queen Victoria)
Check your coin again. Queen Victoria died in 1901.
The value for a well preserved one could be around $250- $300.
Such a coin does not exist. Queen Victoria was not born until 1819 and did not become queen until 1837. King George III was on the throne in 1800.
Please post a new, separate question with the coin's date and country of origin. Without that information it's not possible to provide an estimated value.
The only way to know is to have it appraised.
I imagine this to be a coin set in a mount on a ring, but the description is incomplete. If it is a coin it is probably a sovereign. Modified coins have no collector value.
Well people say nothing but I've been looking around and in outstanding condition 10 English pounds, or 7 dollars..
Elizabeth 11 Regina silver 50 cents
1901 Victoria dei gralla Regina.what's it worth?
Please check your coin again. The first Florins were issued in 1849. MDCCLXXB tells me the coin is 1770 something, 40 to 50 years before Victoria was born. The "B" on the end is a typo and does not exist in Roman numerals. It should be an "I" or a "V" or a combination of both, or maybe another "X".
Victoria reigned for about 60 years and there were about a dozen different coin denominations struck so you need to be a lot more specific. Please post a new question with the coin's date, denomination, and condition.
