Apparently the portraits on the Chilean coins were redesigned in 2009-2010, and at that opportunity, the designer's name was removed.
I got a handful of Chilean pesos last autumn, and all <2009 have the designer name and all >2010 are without. It's very well possible that 2009-2010 were transition years in which both types were issued. In that case, the Numista catalogue might not be adequate.
Would be interesting to find out how many Numista members have Chilean coins from 2009 and 2010, with the indication if it's with or without designer name.
I'll make a start myself. These are two 10 Pesos 2010 which I have, with and without designer name (redesign on top):

I have no other 2009 or 2010 Chilean coins. Who has?
