Question for tube tester gurus

I've seen any number of Hickok 539C's sell on Ebay for well under a $1000.

Can anybody tell me why this one sold for $13k+?

That's what I was thinking, but it would have taken the 2 highest bidders, both screwing up their bids.

As in both of them
$13,433.33
$13,333.33

entering in those bids instead of $1333.33 and maybe $1450.

In addition, the seller's already left the buyer this feedback:
"Fast payment and good communication. An excellent ebayer. A+"

I was just so stunned by the price I figured I was missing something in the auction listing. But I still can't figure it out!

 

Check this out!!

Here's a great example of the insanity that can drive Ebay prices, and how silly things can get!!


My curiosity got the best of me and I decided to contact the seller last night, and ask him what the deal was. Here was his reply:

"You're not the only one to ask that question.

"There is nothing special about my tester other than that it was in very good condition. The 2 high bids were both errors by the bidders- the actual selling price was $1,300, not $13,000.

"I notice that there's another one on ebay that's currently at $1800. In my opinon, that's too high. The high bidder, **********, only bid $950 for mine, so I can't help but think that he's being influenced by my apparent selling price."



And here's that new auction, and check out the bids (no mistakes here, now) of buyers/speculators who've pushed the price of this one over $2k trying to jump in on the 539C craze!

How many of those bidders do you think know the $13+k final price of last week's was a mistake, and the real buyer never paid that much?

If you own a 539-C, you may want to sell it high while you can!

 

Well said, and I think you've nailed it.

But at least with some of the amp prices you see you can sometimes attribute it to the "latest/greatest new amp discovery factor" or "discontinued/short supply factor" or "guess what recording artist is now using the amp" factor.
