Interesting coin tonight

Took me a little while to identify this one.  I had to go get a primer on Chinese numerals, then figure out how to read dates.  And here I thought coin collecting was just fun - now I find out it's educational as well.

7 rolls of nickels

1946-D
1953
1981 Taiwan 5-yuan

7 rolls of pennies

42 pre-1982 coppers
