PERU - Republic Transitional Coinage Gold 1862-1869

Set Description
(The Competetive Sets area does not have a 'place' for these yet so I am posting this here while I request a Competetive Registry Set be created by NGC.)

These gold coins were issued with the same design in two different monetary systems, Escudos and Soles, with the same dates, but with different gold contents depending on the monetary system.

Set Goals
I have obtained most all that are obtainable with reasonable time, patience, and money What I am missing is the great rarity which is the 4 Escudos 1863 which I will most likely never own due to both it's extreme rarity and it's high market value. A secondary rarity is the 20 Soles variety that NGC calls a 1863/9 overdate (punch error) but many other experts say is actually a 1869/3 overdate (true overdate). Don't have that one yet either but ... :-)
