High Versus Low Rx?

Okay, I know it probably seems like I didn't have to search long, but I actually just stumbled across this after looking for something completely different.

I hear you can trade in several million R1s for some higher are values.

lol - yeah Conder. You mean you're not all waiting here at my beck and call!?!?! OUTRAGEOUS. ;)

In retrospect, since it really concerns classic coins I probably should have posted there. I thought (when I was posting) it was more suitable for the general forum. =)

I actually picked up an R6 Fugio last year without even knowing it. Attribution over ebay pictures is tricky - especially in the grades I tend to afford! - but it's a fun challenge. On the other side, I picked up what I thought was a 1796 NC2 in fair for over $100 and got burned as it turned out to be a rather common variety. Then again, I picked up a 1798 missing the 8 that turned out to be an S-149 (R5+) for about $30! It's a fun game. =) I've learned a LOT from it.
