I'm not an expert, but I do have a pair of orange globes. The second pair is orange globe, the first, I believe, is not. The price of the second is hard to comment on, because it is a "start bid" price, so no telling what the final sale price will be. I paid about $65 for my pair, which seems like approximately the going rate. I bought mine on eBay and was fairly confident they weren't fakes because the seller had lots of positive reviews and was experienced selling tubes, and provided lots of information about the tubes, testing information, etc. Others on the list can probably do a better job telling you specifics about what to look for to determine a fake. The orange globes do indeed sound very good. I also have a pair of Amperex PQs that sound as good as the orange globes, but somewhat different.
