The 1975 5-Peso coin is questionable, nickel is not attracted to magnets, the 1944 and 1945 Phil-Am 5-centavo coins are nickel coins and do not cling to the magnet. Anyway thank you very much for the other information re Marcos gold coins, probably it is harder to find and surely cost expensive. My friend is offering me a 1976 Marcos 25 peso coin, claiming it is silver, is this true? and in case, how much should it cost.. Thanks again for the info..
