There are 4 coasters in this set. I don't know where they are manufactured but the package says they are printed in the USA. The printing is slightly off-center which is sort of acceptable to a degree. The slightly worse issue is that one of the 4 coasters is smaller in diameter than the other 3 by about 3/32". That doesn't sound like much but they slipped out of my hand when I tried to pick up the stack. I assume because your grasp 'expects' them to be the same in diameter? 
I bought a set of the coasters called "Americana" at the same time. Same type, same manufacturer, same issues only this set's graphic was slightly more off-center and the one coaster that was smaller than the other 3 was 1/16" smaller instead of 3/32” smaller.
