I recently bought a coin on ebay - 1 crown, queen Victoria, 1897 (KM#783), which looks a bit suspicious:
Obverse has about 70% of queen's bust visible very well; reverse has almost all the details, very nice. Coin is obviously cleaned, but it's expected.
However, what's strange is, edge doesn't have anything on it - no regnal year. Moreover, it has a clearly visible seam all over it

Everything else about it seems normal - weight is 29g, diameter is 39.10 - a bit more than it should.
Is it normal? Is this coin likely authentic, or probably consists of two parts mounted together?
Thank you,
Sergey
