Oh, what a lovely question! The value of a 1948 florin can vary based on its condition, rarity, and demand. I recommend reaching out to a reputable auction house or coin appraiser to get a better idea of how much your beautiful coin could fetch at auction. Remember, each coin has its own unique story and value, so enjoy the process of discovering its worth!
Very little value... they were made in their thousands !
I will assume that you refer to the 1942 British Florin. The obverse has "GEORGIVS VI D : G : BR : OMN : REX" which is heavily abbreviated Latin for "George VI, by the grace of god, king of all Britain", more or less. The reverse has ":FID:DEF::IND:IMP:" which is a continuation of the obverse legend, abbreviated Latin for "Defender of the Faith, Emperor of India". All British silver coins from 1937 to 1946 inclusive will have the same inscriptions on the obverse and reverse. All British nickel-brass and bronze coins from 1937 to 1948 inclusive will have the combined inscriptions on the obverse.
Assuming you mean a British shilling, about 10 cents or so. 1948 shillings have no silver and are very common.
The 1948 one shilling coin from the United Kingdom contains 50% silver, with a total weight of 5.65 grams. This means that it has approximately 2.83 grams of pure silver. The coin was part of a series minted during a time when Britain was transitioning away from silver currency.
Modified coins have no collector value. Any value would be associated with the ring as a piece of jewellery. The 1948 British Florin is made from a copper-nickel alloy and, in perfect condition (not as part of a ring), it might get up to £8 GBP.
A British 1948 cupro-nickel Florin (Two Shillings)(George VI), uncirculated and in absolute mint condition could fetch up to £8 GBP. If it has been circulated but still in good condition, it might fetch up to £1 GBP. The values quoted are the best possible for the best specimens in their grades, but may be significantly lower due to varying demand for the coin and the prevailing economic climate. A reputable coin dealer will be able to give a more accurate valuation based on inspection of the coin.
