Hello,

to CCF!
Why do you ask? Are you finding the coin impossible to find or think there is an error in the description?
Numista's page only shows subtle differences in the lettering of the 1995 and 1997 coins and it's not clear if that's the difference between types:
https://en.numista.com/catalogue/pieces1520.htmlNGC's pages describe the #154 as copper-nickel-zinc (I assume not magnetic) from 1986 only and #154A as nickel plated steel (strongly magnetic) from 1995 and 1997:
https://www.NGCcoin.com/price-guide...duid-1415300https://www.NGCcoin.com/price-guide...duid-1415528I would assume the difference in the types is the #154 is non-magnetic and the #154A is magnetic, but it's not clear if 1995 was a transition year.
I just checked images from my collection and have one that matches #154A but I'm not sure if that's accurate and since they are images only I can't check the magnetism.
