True, but how many rarities exist in the period around 1860? I can think of more right now that I can count on both of my hand, whereas the rarities of the 'modern era' are far and few between.
While there might be less collectors, there are far less different rare examples to be had. Most of which are not that rare but still fetch a little premium, the undated 20p, kew gardens 50p (which the RM unecessarily blew out of proportion IMO).
Pete, off the top of my head;
- undated 20p
- kew gardens 50p
- 1983 new pence 2p
- Aquatics 50p with waves over the face
- (a little less known) 1992 10p with 1 point to bead (broad rim)
I'm sure there's a couple more
