After seeing the latest photo of the 1 kurus coin with regnal year 25, I can agree that the coin in question is probably this one, and genuine, with some kind of error obscuring the 1 in the date. This could be confirmed by measuring the weight (2.7-3.0 g) and diameter (28 mm). My guess is that the coin itself is worth a few dollars, and slightly more because of the error. My 2006 Krause gives a book value for this coin (Turkey KM#597) as $6 in VF. This could have gone up a bit over time, and I think the error adds some value, but coins also often sell well below book value.
