Hello everyone,

I have no idea where else can I post it to have an legit opinion.

I found mahjong in charity shop and it was so interesting that I decided to buy it. Problem is that I don't know anything about mahjong.

Did a tests suggested by Al and apparently it seems to be a porcelain/ceramic one. Tested it with red hot needle which didn't leave any mark on it and just slide on surface, also checked density which is 2,17g/cm³ (which also matches Chinese porcelain range).

Can anyone tell me anything more about it and also if anyone got an idea what would be the value.

Kindest regards

Why did I get this one wrong? My thinking is to get rid of the 9 of bamboo since it's an end tile and doesn't have a straight next to it where the eight and nine pin are one away from a straight. Why does Riichi City think it should be those two tiles?
