The saint gaudens or the gold liberty

I have alot of commons i want get rid of and replace it with a NGC $20 Saint

Gaudens and or Liberty. And was wondering which would be a better fun

build slowly of course but not difficult.

In my opinion the fractional the $2.5 $3 $5 gold seem to

me not worth the effort

Cause i think they are a bit over priced but i havent really countedtihem out yet

I just want to build a gold set not modern cause i am very unhappy with the modern coins
