Doing a little research after my above comment.I discovered that someone is selling  what they are calling a Conquistador  pendant on EBay that matches your piece right down to the hole and crude shape.They said it was found in the desert and are asking a five figure number for it.  Quite a story . It looks more and more like  a tourist piece that someone is trying to scam off of.

I have a similar piece 18mm  1.63g . I have not had any luck in finding when and where it was made. I assume it is some type of decorative ornament or game piece.At least it has a brother.

Looks like Cilician Armenia Hetoum I 1226-1270.

I think Amarmur is on the right track.It looks like a Lithuania schilling John II Casimir Vasa   KM 50 1660or1666. 0 and 6 look alike on those coins.They are also listed as Polish Lithuanian Commonwealth 1/3 grasis  by other cataloguers.Good spot Amarmur

I think your coin can be found in Corpus Nummorum Italicorum (there are a number of volumes).You can find a free online version at Numiswiki and probably elsewhere.It is on page 277 no159 The legend has the same spacing as your coin . There is a dot after the first A (might be off the edge or worn off) If you never been to the Corpus it’s hard to navigate but worth a trip.There are multiple variants of your coin type.Hope this helps.

I think it might be  a match up for Caracalla SNG Levantine 743 Seleucia ad Calycadnum Cilicia 198-217 AD

The Cuenca mint mark star above chalice is to the left on the lion side.

 I think what you have  is from India Nagas of Padmavati 240-350 AD. You can have the fun of determining the ruler from the legend on the reverse. Hope this helps.

In pre Internet days  you used to be able to purchase these  what I would call exotic coins for a couple of dollars .Most of the time they were not attributed to a specific ruler or date range. My go to reference was "Price Catalogue of Ancient Coins Of Ceylon by T.M. De Silva Abeywardene published in 1952 41pages, 10plates. The Plates are crude compared to the beautiful photos of the above posters. Prices were outdated. This small paperback has its own charm and served me well as I collected these interesting coins. Kandy got it's name from the anglicized version of Sinhala Kanda Uda Rata (meaning the land on the mountain )or Kanda Uda Pas Rata( The five countries on the mountain).
