looking at the denticles it looks like it was struck against another coin become pmd and then struck again, ,any oth er ideas ,thanks
It looks like a die clash, but I haven't looked it up. Or maybe it could have been struck over a different coin?
Looks like a massive clash. Here's a 20 centavos from 1920. It's listed as atypical & yours is stronger! http://www.maddieclashes.com/ADC-CL20c-1920-01.html
didn't we already answer this here? https://www.cointalk.com/threads/tis-one-is-very-interesting-coin-from-chile.256787/
no its just when I got the coin I looked through it and I thought there was something else to the coin besides the die clash,.........
