Costa Rica 25 Colones [επιλυμένο]

Costa Rica 25 Colones 2nd coat of arms; non-magnetic KM# 229a has a deceiving title ( I mean Non-Magnetic portion of it). Year of 2007 is in fact magnetic. Someone even added a note about it's magnetism in french on the coin page:

Anyone has a non-magnetic version of 2007 Costa Rica 25 Colones or KM# 229a.1 stands for Brass plated Steel?
