Poland 2 Zloty 750th Anniversary of Krakow 2007 Coin - Nordic Gold


From Poland

Some info on NORDIC gold :-

is actualy as described by wikpedia as
Nordic gold is the alloy from which the middle three denominations of euro coins, 50 cent, 20 cent, and 10 cent coins are made. It has also been in use for a number of years in other countries, most notably in the Swedish 10-krona coin (hence the name).[1] Its composition is 89% copper, 5% aluminium, 5% zinc, and 1% tin.

It contains no gold , this is unlikely to cause many misleading trade descriptions since its colour and weight are quite unlike real gold. It contains too much zinc to be a form of aluminium bronze. Its advantages include antimicrobial action and its resistance to tarnishing. The alloy and its tradename are the intellectual property of the global metals and manufacturing group, Luvata.
