Theft of original license plates - is this an issue?

[Curt phillips]

I have a 29 Tudor that came with the NC rear tag & a front Charlotte
Tag , both original not repainted! Though about redoing them , don’t know if that’s a good idea or not . Both pretty straight just very light surface on the rear tag.
Saw a NC tag on eBay & it to was pricey I thought. I liked the color of the NC
