I have been working on my birth year (1941) set for quite a while. My only catalog is Krause 43rd Edition. I'm trying to ID my 1 centavo coin of that year. There are two varieties listed but only differentiated as Thick Planchet or Thin Planchet. My assumption is that they weigh different. Krause doesn't give me that info. Can someone give me those weights? ALSO I'm trying to ID my 2 centavos coin of that year. There are two varieties listed but only differentiated as Thick Planchet or Thin Planchet. Same problem as the 1 centavo coins; same assumption. Can someone give me those weights? Also if there's a website that gives more specific info on Peruvian 1941 varieties that you know of, it would be great if you could give me that link.
Does your coin have a mintmark? Mintmark C is the thick Planchet. Note in comments. https://en.numista.com/catalogue/pieces9062.html
Thanks for taking a look. That's the coin with the curved CENTAVOS. It's the one I have. The ones I'm trying to figure out the varieties of are the ones with a straight CENTAVOS. Doesn't appear to be many Peru specialists. I've got one other site I'll try.
