I have been considering car number plates for some time, and have noticed some of the four (4) digit number plates have not been selling as well as, say two (2) years ago. However, they still tend to be in the $10-20,000 range with some asking more for the '3's and '8's combinations. Whilst I realise that in a true SHTF event, they will be rendered essentially worthless, is there potential for capital growth over the next few years as money flows out of the share market/real estate/banks etc and into alternatives? To clarify, I am interested in numeral number plates only, and not the vanity types. Any opinions?
