Need information for golden coin like 25 Kuruş Muhammad V Reshad [solved]

6 posts
Hi,
I have a golden coin that looks like this one : http://colnect.com/en/coins/coin/31429-25_Kuru%C5%9F-1909~1918_AH1327~1336_-_Muhammad_V_Reshad-Turkey

Diameter: 14 mm



Please help to proper identify this coin
Depending on weight/diameter it is the following coin: 50 piastres, 100 piastres or 250 piastres AH1277 regnal year 8 (= 1867). Reign of Abdul Aziz (AH 1277 - 1293 / AD 1861 - 1876). They are all .917 gold.

It can't be 25 piastres because this coin has no regnal date 8.
It can't be 500 piastres because this coin has on the bottom of the obverse "500" in Arabic.

When the pictures in Krause are in actual size, the diameters are as follow:
50 piastres: 17 mm
100 piastres: 21 mm
250 piastres: no picture in Krause

Weight:
50 piastres: 3.6080 g.
100 piastres: 7.2160 g.
250 piastres: 18.0400 g.

100 piastres: https://en.numista.com/catalogue/pieces22156.html KM# 696 (Y# 17)

50 piastres (Y# A16) en 250 piastres (Y# A17) are not in Numista yet.

Note: in Numista they talk about "kurus" in stead of "piastres" (Krause).
Quote: ka7terDiameter: 14 mm
Sorry, I overlooked this.
But now there is a problem.  The 50 piastres has a diameter of 17 mm in Krause. But their pictures are not always in actual size. So that could still be possible. But the 25 piastres here on Numista (https://en.numista.com/catalogue/pieces52702.html) gives a diameter of 15 mm and it  is  very doubtful that a golden coin with a higher denomination would be a smaller coin because with golden coins it's always about weight.
The diameter of the 25 piastres would fit better, only the 25 piastres AH 1277 has no regnal year 8 (at least not in Krause).
Thank You for the reply,
I did another measurement and this coin diameter is 14,8 - 15 mm.(my fault  z| )
There is a difference in the coin in the place marked with red (in fact the surface is emty, no signs) in comparison with http://colnect.com/en/coins/coin/31429-25_Kuru%C5%9F-1909~1918_AH1327~1336_-_Muhammad_V_Reshad-Turkey :

What does it mean? At least now I know that it is rare coin.
Thank You in advance.



 
That is because you are comparing it with another type of coin. The one in your link is about 50 years younger than the coin you have: 25 piastres AH 1327 regnal year 2, with "Reshat" to the right of the "toughra", Y# A51. The "toughra" is that big symbol to the left of your red circle that you commonly see on Turkish and Egyptian coins. "Reshat" is the honorific title of Mohammad Reshat V that appear on his first coinage.
Coins with accession date AH 1277 (like yours) have an empty space to the right of the toughra.

But your problem stays. The diameter fits with the 25 piastres AH 1277, only that coin has no regnal year 8 according to Krause.

Maybe someone with a higher expertise on Ottoman coins and a more specific catalog about these coins can verify if that regnal year 8 exists for that coin or not?
Thank You once again!
