I kid you not, but there is a fair trade in old tax discs, some peeps actually collect them and pay good money, was reading an article about this around 2 weeks ago (Tax disc monthly or similar I guess)......obviously most were trainspotters until most trains stopped running I guess. So don't glue them to anything. Actually it was the Telegraph, just found it online Could your car tax disc be worth £1,000? - Telegraph
I had someone ask me for a car tax disc holder yesterday.You won't need it as of tomorrow.But I want to sell it with the tax on it.You can't tell em. I ran them out two weeks ago so no stock to throw out
