This question doesn't have enough information for an answer because you didn't mention the coin's denomination. Also, it's redundant to ask what the value of something is worth.
While you included the entire inscription on the obverse, this question is missing the more important part: the denomination.
In circulated condition, your Great Britain penny is worth about 50 cents.DanUser:WorkingMan
George V coins were issued from 1911 to 1936 inclusive.
I do not think it will devalue the stone any, but it has certainly devalued the coin. Modified coins have no collector value.
A 1918 Georgivs V British coin with a denomination of 25 would likely be a silver crown coin. In poor condition, such a coin may have significant wear, damage, or corrosion, which can reduce its collector value. The value would depend on the specific condition and rarity of the coin.
If it has both George V and the year 1900, it is a very poor fake. George V did not appear on British coins until 1911.
Check your coin again. Queen Victoria died in 1901.
It is Latin, but abbreviated. The expression "GEORGIVS V" identifies the reigning Monarch of the period, in this case, King George V. It does not identify the country or the denomination of the coin. "DEI GRA BRITT OMN REX FID DEF IND IMP" means "By the Grace of God, King of all the British territories, Defender of the Faith, Emperor of India".
Your coin is from the U.K. and assuming it's relatively worn from circulation it would retail for $2 to $4. The inscription is heavily abbreviated Latin for "George the Fifth, by the Grace of God King of All England, Defender of the Faith and Emperor of India". Whew!!
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.
Other than for very minor differences, all British Halfpennies minted from 1911 to 1925 should be almost identical. See the link below.
Well people say nothing but I've been looking around and in outstanding condition 10 English pounds, or 7 dollars..
I am unaware of any British Empire country that uses the Peso as its currency. The inscription is Latin, but abbreviated. The expression "GEORGIVS V" identifies the reigning Monarch of the period, in this case, King George V. It does not identify the country or the denomination of the coin. "DEI GRA BRITT OMN REX FID DEF IND IMP" means "By the Grace of God, King of all the British territories, Defender of the Faith, Emperor of India".
