Is this Mehmed V gold coin a genuine error ? [solved]

A fellow had bought this gold 25 kurus 1327 ,Mehmed V ,from a jewelry shop few weeks ago . The coin has a obvious minting error and this made him impression, so he brought it to me in order to view it in person . In a closer inspection the difference of the shape of the toughra ,the digit under it ,decoration and other parts of the coin made me suspicious whether the coin is genuine at all or it's only a contemporary counterfeit .

Still if it was made by a forger whit the intention to desive someone why does it has this striking minting error? The weight is not different, from the regular ones it is exactly 1,80 gr. ,the diameter is 15 mm. Could someone please say what can it's value be if it  is a counterfeit or  genuine error ?

The reverse of the coin is a complete mirror image so is back to front, the toughra looks about right to me but below it is ‘sana’ but the regnal year is represented by a weird horizontal oval. There is no way a genuine machine struck coin would have such errors and the actual engraving quality seems not very sharp which is another clue as to it's method of producing this coin.

A dim witted modern forger might have simply copied a coin without realising the dies have to be engraved as a mirror image

Thank you ,for your opinion and the information you have gaved in your post.  I think that it's most logical one.

COmpare details of the toughra side.  Very poor fake.

Thanks to the discussion I can say that now I don't have any doubts that it's not  a authentic coin ,all argument are leading  to this conclusion. But still I'm curious are there any collectors of such imitations,fakes of Ottoman gold coins ?

As far I know it's made from gold,so does it have any additiona value, more than the material from which it was made ?

If it's tested and found to be real gold then the question would be what would a forger gain from producing it? Usually fakes are made with a base metal and then plated in silver or gold.

I would suggest it's perhaps made by a jeweler for mounting on a chain etc, then deliberate errors are made so as to avoid being accused of forging local currency. Indian mohurs and rupees with deliberate errors were used in jewelery and l have examples of some of these myself

Pieces struck for jewelry are also known for Ottoman coins:

In fact, this one is similar to the OP's coin (though without the reversed impression):

Yes ,in most of the forged gold liras I have encountered were made ,from bronze or other materials with some type of thin gold plating . I friend of mine a antique shop owner ,had I a small cardboard box filled with such contemporary counterfeit Reshad coins, they all had tresses of gold plating. The most easy way to detect them I know is by there weight, all of these fakes have lighter than 7,20 gr. weight .

Vic65 in this case I'm inclined to agree with you, that this could be a jewelry imitations for decorative purposes . The difference in the design maybe conferems this as stated in yours and tdziemia posts.
