Ethiopia 50 Santeem 1996,1997 Copper-Nickel vs plated steel [solved]

Copper-nickel: https://en.numista.com/catalogue/pieces4759.html
plated steel: https://en.numista.com/catalogue/pieces63353.html

According to the Numista pages both types were issued for both years (and collectors are recorded as having the types). The references are KM# 47.1 & 47.2, Schön# 54 & 54a.

But I looked a both KM and Schön and neither lists the non-plated version.

Does anyone actually have a non-magnetic 50 Santeem dated 1996 or 1997? (Is there a way to check the collections to see if anyone claims to have both types?)

EDIT: I have the 1996 and 1997, but they are both magnetic steel.

​Thank you for checking.
