Vintage miniature solid gold COIN 8K Enrico Berlinguer very special
Vintage miniature solid gold COIN 8K : Enrico Berlinguer very special!! Good quality, signs of age. Please see all the fotos. 8k gold could tarnish from sulfur and ammonia in the atmosphere. Copper, in particular, likes to react with oxygen (moisture) and this can lead to discoloration or tarnishing greenish to brownish. This is normal process. The coin is over 40 years old. The measures of the Gold COIN 8K: 1,1 cm / 0,3 inches diameter. From my personal collection. Very special and rare to find.
