I want to start, but finding the coins to fund coin collecting is a little tough. I know where I can get 2 loose (R2-D2 and Barada I think), but have had other priorities. While they are only $15 for the pair or so, I always have found higher prioritites.
I have just finished submitting an extensive (maybe beyond extensive) checklist of all known coins (rare, prototypes included) and it will go up with an entirely revised vintage set of checklists on this site in the near future.
And poor you, DSJ, only having 5 carded...
Hope I can say that someday. Vintage collecting is a dream, hope I can find the $$$ to fund such a paasion someday.
