In PA, They allow you to register vintage plates on your car. I looked on eBay and found a vintage 69 plate and after checking the PA DMV website to make sure the plate numbers weren't being used (just like for vanity plates) I was able to register it as an antique (no emmisions, safety inspections or yearly registration charges) and display a vintage plate with the '69 sticker on it. I am not sure if Tennessee allows that, if it we're me I'd check.
