This could be written more cleanly (although arguably not as readably) as

name = plural.get(name, name + "s")

d.get(key, default) returns the value from d mapped to key if it
exists, or default otherwise.

You might also want to split your calculation and display code into
two separate loops.  This might seem wasteful, but it will make your
code easier to read and maintain, and the waste is only marginal with
the loops you're running - there is a maximum of only 17 passes (once
for each value of coin and note)
