Very nice post. I started collecting in the mid-90's when I stumbled upon a 1973 $1 bill after a long time. Then I just had to get the $2, the $5, etc.
Now I have almost all but the rarest of Canadian notes.
Unfortunately, with the coming of TPG's and "some" dealers' ways of doing business, lots of new collectors come in this hobby thinking it's a gold mine that they are going to suck out of enormeous amounts of money. This one kid ask for scans of a whole bunch of notes (worth thousands a piece) and then made me an offer on the cheapest one that was a fraction of the value (really, a fraction, like 1/4). His argument: He doesn't have any money. But everytime I post something in the trading forum, he asks me for scans. I just go on and ignore him. Then he asks me if I'm looking for a 1887 $2 note, a 1924 $5, etc. Why? So he could look for them and resell them to me? lol
