what is on the reverse, and what is the size and weight? it could be a soveriegn but only further information will lead to a definite ID
Looks like a sov by colour & inscription (bronze coins have the full inscription, but spell out FID: DEF, for example, so it's not one of those), but as moneyer says, we'll need the reverse details to be sure. If it contains George & the dragon with the date in exergue, it's a sovereign (or half-sovereign). Look also for a small letter between the middle two digits of the date above, under the horse. If none, it was minted in London. Other letters could be M=Melbourne, S=Sydney, P=Perth, C=Ottawa. A full sovereign contains 0.2354oz of gold, and a half sovereign half that amount.
yay my coin has the date 1909 and the some guy on a horse slaying a dragon, hard to tell what letter is on the back. is it 10kt 14kt 18kt or 24kt gold how can you tell if it is a half sovereign
1/2 SOVEREIGN - 3.9940 g., 0.9170 Gold 0.1177 oz. AGW SOVEREIGN - 7.9881 g., 0.9170 Gold 0.2355 oz. AGW
22 carat gold, .916 fine gold. There may not be a letter - if that's the case, it's a London sovereign. Best to weigh the coin if you can to get its weight and therefore whether it's a half or full sovereign.
There are many fake coins in the world, most people do not come into possession of a gold coin with out knowing everything about it. How did this coin come to being in your possession? Where it was found and whom last possessed it could answer some questions.
i was traveling in cuba of all the places and some one said he had some old coins and i took a look at it and got it, the person i got it from is a jewler in a small town in cuba and he didnt even know it was gold becouse it was realy dirty i am the one that took off the gook.
If a magnate sticks to it, it is definitely fake... If it passes that, you should weigh it on a scale accurate to at least .01 grams next would be to closely compare it with other known real examples and/or mail it to a reputable Third Party Grader. I.E. PCGS, NGC, ANACS, ICG..... Although if you only want the gold weight value, you could have it acid tested for gold purity at most any jeweler.
