I have this Turkish - Ottoman Gold Coin, that appears to be a 500 Kurush Coin from the year 1327/1912. The thing is that its diameter is 34mm and its weight 30.1grams or 1.06oz. I can't find these characteristics in any catalogue. The proper 500 Kurush Gold coin should be 36grams in weight. So, can anyone can help me identify my coin ? Thank you.   |

Welcome, dreampress!
First of all, the date is 1327/1 (not 4), so that would be AD 1909.
Second, the weight should be 17.54 grams, not 30 or 36. It was this weight for the first 6 years of reign of Muhammad. On the 7th year, in 1915 it would get heavier, 36.08 grams.

Thank you very much for your answers. The thing is that my coin is genuine ( I had examined by a gold specialist ) and its 34mm in diameter and 30.1grams in weight. I bought the Krause World Gold Coins Catalogue, but I couldn't spot it anywhere. Any clues ? I realise that they were some MONNAIE DE LUXE Gold Turkish Coins with a lightly less weight. Could it be one of those ?
Thank you.

Sorry, guys, but the weight given in the Krause catalogues for KM# 758, the 500 kurush dated 1327//1 to 1327//6, is wrong; that's the weight of a 250 kurush. It's an error in the catalogue. If you take the (correct) weight of a 250 kurush coin from the same year (18.04 grams) and double it, then a 500 kurush coin should weigh 36.08 grams, the same as all the other 500 kurush circulation coins in the catalogue. 17.54 grams is the weight of a Monnaie de Luxe 250 kurush, which as dreampress reports, is actually lighter than a "normal" coin of the same denomination.

The thing is that my coin is genuine ( I had examined by a gold specialist )...You seem to have mis-recorded or mis-interpreted your information from the jeweller you had it weighed at, since you have in fact given us the correct Actual Gold Weight of the piece: 1.0638 troy ounces. If this number were converted from avoirdupois ounces to grams, you'd get 30.158 grams. But that maths would be wrong, for two reasons: gold is weighed in troy ounces not avoirdupois, and this coin is not .999 fine it's only .917 fine. Your coin should actually weigh 36.08 grams, and contains 33.09 grams of gold.

OK, thanks, I see the discrepancy in weights now, corrected my Krause (Have they ever corrected it in any edition?) There was a discussion earlier about the same coin, the owner there confirmed the wrong weight of his/her coin, but I think (s)he didn't really weigh it. As for Monnaie de Luxe, not only they are lighter, they look significantly different, so there wouldn't be a question whether this coin is one or not. |

This is a very familiar discussion :)
And - the same answer at the end too...

Like many collectors, I'm a member of various coin forums and questions about this type of coin seem to be appearing with increased frequency lately.
In some cases it's just one coin, in others a buried hoard has been uncovered. What they all have in common is a weight discrepancy. Should we be concerned?

It's Krause that's wrong - not the coins :)

If the coin does indeed truly and actually weigh 30.1 grams, and the balance used to weigh it is trustworthy and has been properly calibrated, then the only conclusion that would be reached is that the coin is not genuine. If it tests well for pure gold, then I suspect the likeliest explanation is that it's a jewellery replica, made of solid gold (though perhaps not the same fineness as the original coin) but privately made and not a legal tender coin.

I don't know when the error crept in; probably when many of their errors crept in, when they went digital and split the book up into separate centuries. It's still wrong on the NGC data page which uses current Krause data, so I'd assume the answer is "no".
