1874 Swiss Schützentaler (Shootingthaler) Obverse and Reverse differ

Hey I stumbled across that shooting Thaler coin in Singapore and naively thought it must be very rare to find. Now that i checked more I found the obverse and reverse are from different years (st.gallen and Lugano). But coin is non-magnetic, the "ping" is nice and the ice test melts also very quick. Did i Fall for a fake?

Weight? Diameter? Thickness?

37mm and slightly above 2mm. Dont have a good enough wieighting scale atm. I found on alibaba a slew of them, which would explain the two differing sides. Sadly i think its a fake
