Title: Peru, 10 soles, 1982, Lamination flaw
Post by: Gusev on December 20, 2015, 03:47:40 PM
Many modern coins are made of layers of different metals known as clads. These cladding layers sometimes peel, fold, or completely separate.

Wow, impressive error. KM says this coin is brass, which is made of at least two metals, but it does not say that it is a cladded coin. The cause of the error may be season cracking (https://en.wikipedia.org/wiki/Brass#Season_cracking), faulty annealing or bad quality metal, with a pollutant causing the crack in a very high or low temperature environment (possibly a laundry).

This coin for circulation. I got this coin at the bazaar in Lima in 1996.
I like the version of the Laundry.

Lamination flaw I think.
