Do any of these plates actually ever sell?

I have had "SMOOTH" NSW custom plates since 1983 (or whatever the first year was in NSW for these plates). Started at $150 per year plus the original order fee (Now around $500 per year).
I have had them on offer on MR PLATES for over 12 months with one single enquiry (he wanted then for less than the annual lease fee!). Over the years have also had many personal plates and never had any decent offers.

In NSW the plates are now sold/leased by a private company and it's one of the biggest rorts going.

I'm with you Max, the NSW historical (bike rack) and conditional (tractor) plates in NSW are the ugliest plates they could muster.

Yeah, good luck selling your "SNDMAN" plates at any price. The VIC system is much better than the NSW version though, so you have some chance I guess.
