Here what I found:
Canadian collectors normally use the terms magnetic, to describe steel-cored cents, and non-magnetic for zinc-cored cents.
The 2005P non-magnetic coins were created when the
RCM struck coins on zinc-cored blanks using dies intended for steel-cored blanks. It is not known if the errors were created when the wrong die was used, or if the wrong blanks were used, or if just a few zinc blanks got mixed in with steel ones, but very few 2005P non-magnetic coins are known to exist.
Your exact coin is selling on this site for $2,995.00. How much did you pay for it...
