Looks Islamic to my not very learned eye. Someone with a passion for this type will swing in to answer in a bit I'm sure. Very cool design, whatever it may be!
The upper photo is not coinlike. But the lower photo shows a coin with the islamic year 1255, that is 1839 AD, the first reigning year of Ottoman Sultan Abdul Meijid. That date is on many of his coins.
Thank you Pellinore. Yes I think the same about front not being coin like. But they are front and back picks. It is about the size of a 50cent, thickness of a 10 cent and has divots around the side like a coin. I have searched the Internet and can’t find anything similar.
As @Pellinore said, this has once been a 19th c. Ottoman copper or brass coin, likely a 10 para coin (like this one here: https://www.vcoins.com/en/stores/wa...852__abdul_mejid__10_para/387059/Default.aspx) or a 40 para coin. It looks like someone actually quite skilled worked it into a brooch by smoothing and afterwards reengraving the obverse, and soldered a pin and a catch onto the reverse. The pin is broken off, but you can still see its base...
It could be the upper photo is upside down. In that case, the fruits (pineapples?) are hanging down and there’s a monogram involving C’s.
Ahh that all makes sense now. Thank you very much for your help Orielensis and Pellinore. I found it a few years ago with my metal detector in a little ghost town in central Qld. If only these things could talk so I could know the story behind them. Thanks again
