Cyprus 1 pound 1997 pink

I bought this banknote for 30 euro

.           Are they worth it?

Here's a pmg 65 that sold for $16.50, so it appears you overpaid:

PCGS has mislabelled your note as P-57a when it is P-60a (due to the 1997-Oct-01 date) & L000173 serial number.  So it is the first of the revised (orange back) 1997 notes & much more common.
