Turkish Gold Coin Identification

Welcome to Numista!

The date shown on your coin is AH 1115, corresponding to about AD 1704. The appearance is similar (perhaps identical, not quite possible for me to tell from the photo provided) to an Ottoman gold Zeri-Mahbub or Ashrafi of Ahmad III, for example this one

It's also similar (but not identical) to this one from the Zeno database

However, your weight is far off - you report 2 grams and the coins cited both weigh 3.4 grams. They also both have diameters of 19 mm, while you report 17 mm. I advise accurately rechecking the weight (to the nearest tenth of a gram) and diameter. The top photo should be turned 90 degrees counterclockwise and the second photo should be turned 180 degrees.  

Thank you very much for your help I weighed the coin on my kitchen scales which might not be entirely accurate. I have inherited a number of coins and this is one of them. Would you be able to tell me what the value of this coin is ? All advice is greatly appreciated!

 I cropped and rotated the pictures … 

Thanks for improving the photos, ZacUK. 

Jenny68, your coin is similar to the first one cited above, but differs in some details. Your coin shows more wear and is of a lower grade, though still an excellent coin. It might be from a different mint, which would affect the value. The first coin cited above sold for USD 495. My first guess for your coin might be around $300, if it's from the same mint. We'll need for someone with more experience in Ottoman coins than I have to make an appraisal. 

Many thanks to both of you for your help I do appreciate it, I will try to improve my pictures for my next post.
