As a license plate fan/collector, this is an awesome one. In Delaware you can sell low digit tags on the open market for a lot of money. If you have one of these plates, you can get it as a black plate for $100 or so.
So seeing this plate on this car really got me going - this is a Buick Estate Wagon, probably early 1980s model. One might be able to sell this car for $500, but get maybe tens of thousands for the plate. And it’s the plain yellow-on-blue tag! This person is awesome.
