I'm usually pretty good at figuring out Chinese coins using my World Coins book, but, I can't seem to get a match on this one. I can find most all the symbols, but, not all on one coin. Maybe this is a fantasy piece? Something sold to tourists and not a real coin? I think it's oriented correctly, but, apologies if it isn't.
It appears to be in imitation of one cash coins issued by the Qianlong (Ch’ien-Lung) Emperor, also known by his posthumous temple name Gaosong (Kao Tsung), between 1736-1795. The reverse has an equally stylised version of the mintmarks for the Board of Revenue mint in Beijing. Like this (or, rather, unlike it with the characters having only crude resemblance to the original coins):
I would be sure it’s one of the many variations of more recently produced ‘good luck’ charms in imitation of Chinese cash coins. They’re usually cast in brass and had a variety of uses, but particularly as gifts at celebratory occasions and Chinese New Year.
I was on xianyu. It's a online platform in China to sell second hand stuff. On it, there is a seller who has one for sale. He mentioned, he got it from either North America or Europe and has not seen anything like it and not sure what it is. He is only selling it for 88RMB around $12 dollars US. 7 people showed interest in the item but nobody bough it. Photos of his item:
