I've done a little research, but cannot seem to find my answer exactly.
I've been through currency conversion sites and see that 1 pesos = 10 cents USD (appx).
What are the denominations that are used down there? I suppose the actual question is what is the lowest form of currency?
Not thinking exchange rates, but do they use 1 peso like we use 1 dollar or 1 penny?
I remember buying a bottle of ketchup in Mexico, but I paid on plastic so I didn't have to worry about a whole lot. The price was 9.99 on the bottle (two years ago) and I think it converted to about 1.00 US.
