Hi, I just received some IOM circulation coins, including the 2013-2014 5p and 10p and I guess I already have some final comments about these coins. But first, I will list what I have:
5p:
2013 AA non-magnetic
2014 AA (both AA on same level) non-magnetic
2014 AA (second A lower than first one) magnetic
2014 AB magnetic
2014 AC magnetic
2014 AD magnetic
2014 BA magentic
10p
2013 AA - magnetic
2014 AB - magnetic
2014 BA - magnetic
2014 BB - magnetic
2014 BC - magnetic
2014 BD - magnetic
As reported by multiple users: 2012 and earlier coins are all CuNi (non-magnetic). All coins after 2015 are nickel plated (magnetic) but this was not recognized on time by Krauze/Schon catalogues and it seems new years were added to the Numista page for magnetic versions.
For 2013, it seems that 10p AA (the only one variant of 10p) is magnetic. If anybody has the non-magnetic version, please let me know.
5p 2013 is stil non-magnetic (also only AA known).
For 2014, it looks that 10p is naturally magnetic for all variants as the metal change was in previous year.
For 5p: seems that part of 2014 AA mintage (with AA on same level / "AA right") is non-magnetic and other part of AA and all next die letters (AB, AC, AD, DA) are magnetic.
I just added “non-magnetic” in the title of older versions, so now, users can clearly see that this page is for CuNi coins and for the plated steel is another one page.
I will ask admins to move users of from the wrong entries on non-magnetic coins and to move them to magnetic ones soon.
