I hear you... it would be economically stupid to buy that drum and use it... like uncirculated coins - you don't dare touch 'em.
I guess, more accurately, if someone gave me the drum and I couldn't resell it, then I'd open it and play the crap out of it.
That drum very well could still be in the plastic 50 years from now... THEN some guy will open it and play the crap out it, and say... "sucks, I guess it was a bad one".
