About 100 years ago, there was a batch of 100 misprinted postage stamps in the US (the 'inverted Jenny'). The few that still exist have sold for unbelievable prices; recently one went for over $1 million.

Somehow, I dont see nixie freaks-of-nature hitting that price, but I'm sure there is someone out there who simply has to have it.

It would look interesting to rapidly cycle the cathodes in various patterns.

A demonic style clock crowned with this tube constantly cycling at 10Hz rate (so each digit lights once a second) from front to back. That would look interesting.

Personally, I don't get the "collector" thing. It's nice to have something unique, but if you're not willing to use it, it is just another thing taking up space. I'd buy a trurly rare tube only to resell it.

Not so recently I've visited one market, on which I found some fine grid IN-1s and some uncommon nixies (mostly American, very rare in post-soviet country) for ~3$ each, the price was okay, but having 1-2 tubes of each type is pointless unless I make a Frankensteins Monster clock. 

I spent my money on other gems that day, NOS TESLA gold grid, gold pin E88CC for 5$ each.
