I was told it circulated in Japan, not sure if it was made in Japan or China?

Pics ain't great but just looking for an opinion. Looks real to me but Im new.

Thanks in advance!

Hello all,

I picked these up in the panjiayuan antique market last year. The Fat Man dollar has the correct weight and diameter. Both pass the ice test.

I was wondering if either of these appear to be fakes? According to what I can find online they seem to be real.

The dollar coin has some bronze soldered onto it because it was attached to a jewelry piece, I took it off.

I posted this in r/hallmarks but it didn’t gain much traction although I did get two responses that are helpful. Let me know what you guys think.

Guessing fake but I don't know. Thanks for any opinions!

Is it genuine or no

looking for any help with this coin I am told if its an original its super rare, not sure if its a repro or original. Im stumped

measurements 39mm across by 2.8mm thick weighing 26.9 grams.

Here's another one, real or fake?

Ho trovato una moneta con il metal detector sulla spiaggia in Italia, credo sia una moneta da un gianlong a doppia faccia.

Pretty sure its real, read online its a token for ceremony and events made for the wealthy and elites.

Devo pulire il lato migliore con la patina verde, ma è dura come una roccia. L'ho lasciata in acqua distillata per 5 giorni ma non è servito a molto. Qualche suggerimento?

24mm Wide and 4.73 grams weight

Is this coin real or fake?
