Anybody have any idea what these are?
Anybody got a guess?
Sorry, I wish I could help you.
I am guessing they are Chinese coins or tokens of some kind.
Are they gold or brass?
They must have been made in the PRoC since they refer to the founding of the Republic of China in 1912, and the People's Republic in 1949. My guess would be that they are some historical set of medals commemorating the history of China since 1912.
