For a plate to be worth anything, you need to first find a buyer for it!
.....people like Reg Transfers and Elite are good at telling you what a plate is worth but they are quite often just interested in 'getting it on their books' so to speak.....what they dont say is that they then have to find someone that is interested in buying that perticular number in order for you to get any money.......could take years even if it sells at all!
Its a bit like selling your house......and estate agents.
Try putting an ad on ebay to see if it gets any attention....i normally find that is a good way to find the true value of something.
We have two plates, one on retention and the other on one of our vehicles but we got these, not to make a profit by hopefully re selling later on but just because they meant something to us. Maybe someone will contact us one day and offer us good money for them......but then maybe not....
At the risk of pushing this thread in a completely different direction, i followed a silver BMW last month on the M42 with the plate
'V14GRA'.....the bloke driving it looked real hard.
