Am I insane to do both coins & currency?...
I must admit, I'm glad our Collector's Society fee covers both coins & currency. I've been working on my coins so much lately, that I decided to get my currency caught up, and yes, to buy some more!!!
I originally started out with just United States currency, specifically Silver Certificates and Legal Tenders, mostly all small size. But I'm starting to like more things now, at the top of the list are the Deuces, and Mexican notes. So of course I have to get the more expensive ones, particularly the Mexican Specimen notes.
Well, then I found Canadian notes, especially the 1954 issues with the gorgeous scenes on the back.
For competitive registry sets, I'm planning on sticking with US currency, and make signature sets of the foreign currency. Hopefully the signature sets I make will augment my coin signature sets. But I'm still looking for affordable Chief and Buffalo Notes.
To close, I'm going to attach an image of my only large size Silver Certificate, and the image is the back of the note. I was amazed to see so many of the threads on a Choice AU58 note.
