It looks Ottoman to me--I think it says "struck in Constantinople" & the date looks like AH 1255 = ~1839.

The "1500 AD SILK TRADE TOKEN" is either a Turkey 10 para (KM-652) or 20 para (KM-653) of Abdul Mejid dated AH 1255, year 1 (=1839), Constantinople mint, which was struck in billon, a very low fineness silver alloy. It is depicted rotated almost 90 degrees counterclockwise, obviously by someone who has no clue. In the center of the first photo is the sultan's toughra - calligraphic monogram - almost sideways. (The added floral branch should be positioned from about 1:00 to 3:00.) It's a common little coin, in lousy condition. Dealer's junk box material.

Nothing personal, of course.

Was this included to see if we were awake? Or was it intended for April 1st? Turkey itself wasn't really on the silk road. And what's this about "1500 AD"?

This piece seems to be a billon 20 PARA coin dated AH 1255 (1839 AD), for use in the Ottoman (Turkish) Empire (KM #653). It was issued in the first year of the reign of Abdülmecid I, who came to the throne in AD 1839 = AH 1255 or ١٢٥‎٥ and died in AD 1861 = AH 1277 or ١٢٧‎٧‎.

I have taken the supplied pictures, rotated them, adjusted brightness and contrast, and annotated the result. Now compare with what can be seen at e.g. https://www.ngccoin.com/price-guide/world/turkey-20-para-km-653-1255-1-1255-5-cuid-1114494-duid-1551842

The appearance of the word مصر (Egypt) has me fooled at first – I thought the coin was for use in Egypt! But, of course, "Ruler of Egypt" was one of the Sultan's titles.

The piece has clearly been mounted or connected to a ring for suspension or attachment, see the scar at about 11 o'clock on the obverse or 1 o'clock on the reverse. So it could perhaps be a copy as used in the clothing and scarves/shawls of dancers, somewhat like at http://www.worldbellydance.com/wp-content/uploads/2016/04/Gold-coin-291x300.jpg .

I have to dispute this--that's not Misr (Egypt) but Duriba (struck) because that's what I'm reading as "struck in Qonstantiniyah" (i.e., Istanbul). The first letter is too big to be a "meem".
