Broken Western Electric 300B -- Is there a market for these?

So I bought a matched pair of the reissues back in the late 90s. It was for my Cary Integrated 300B amp. Long story short: after a couple of years, I sold the amp and kept the 300Bs. Stupidly, I mishandled one of the tubes and broke something inside it. There is a rattle in the tube. So I was wondering if there is a market for such things. I have the original reissue box and certificate. 



I think the good one might have some value if you find someone that would want a spare single, but people usually want pairs. Ebay will probably be the best place to try and sell. You do see some of the original singles for sale, but not sure about the reissues. The one that rattles is worth nothing.
