Yes, it's true. My 2001 non-magnetic coin that I supposed to be N#22312
is in reality the Proof one… so the old page (link above) was separated correctly but the description was wrong: bronze is Proof but this was not written on the old page. Instead was “from specimen set”. I don't know what were the old specimen sets, maybe with the prrof coins (the newer ones are with special Specimen finish).
StoneTemple123, thank you for correcting it!
It could be a mess with the moving the users from old page. I guess part of users could not look at finish (Proof/specimen) but rather on composition: magnetic or not, like me… so I would say the best is to merge old page with the one for Proof coins (both bronze). I already switch my coin myself.
Just one thing: I would add to the title rather info about composition/magnetism than “Proof” to distinguuish from normal coin.
