I kinda figured these would bring a high price, but up until an hour or
two from the end it was only a dollar. Someone has gotten themself into
a very expensive hobby.

I'm still waiting to see the day when something like this is shown on
Antiques Roadshow. Or read that they went for some big $$$ at
Christy's.

What *is* the purchaser going to do with them ?

I may have a stack of BC109s somewhere - reckon they're worth anything ?

Maybe build something that is able to run with a VCC of half a volt?

Not yet, they aren't Germanium. I've got a few really old OC
transistors. When building something that runs off a single NiMH cell
they are cool but then again you can also do that with a 2N3904.

The versions in glass packages are nice as well. Scrape off the lacquer
and they become a light sensors. Sometimes no scraping is needed when
the lacquer kind of falls off by itself.

Correction. Almost nobody. Just like spam, it takes only a very few to
make it worthwhile. And those few are apparently willing to pay dearly.

With these particular transistors, it looks to me like they were not
hermetically encapsulated. So it's likely that very few lasted decades
and the company very likely stopped making them soon after they
introduced them. That makes them rarer (I've never seen any of them or
anything like them), and hence what few exist are in high demand.
High demand = high $$$.

And the will continue to be in high demand. Oh, well.

I would say that since they (2N54s) were not hermetically encapsulated,
they are very likely non-functional today.

But your staement "..something that is able to run with a VCC of half a
volt.." brings up something that I wondered about. Back in the '60s
Motorlaa came out with some germanium power transistor that werew for
DC-DC inverters operating off fuel cells. These transistors were good
for 5V maximum, and several tens of amps. These Ge transistors are no
longer available so I was curious as to how it would be done today.
Then I found this.

Seems like most of the germanium transistors in the TO-5 case, in 'NOS'
condition are going for around $1.00 on Ebay. I can't find that # in my
sub manuals, but if it's GE, it's probably common, and not worth much.
The 2N107 and similar go for a few dollars.

Yes, I prefer the glass types. Probably a good glass seal can outlast a
human being in life expectancy. However, I have an old converter that
uses steel case Ge transistors. It is about 40 years old and works fine.

Pretty clever circuitry. That is just the trick, to furnish a starter
circuit. It doesn't even have to be an electronic one. It could be a
piezo button, a relay or something else that generates a brief burst.

I kept a few Germaniums including some big ones. So whenever the need
arises I can whip up the circuitry. It just can't be a design for
production because the few Ge transistors still out there are expensive
and often in limited supply.

Some of the really early transistors made by RCA do go for a lot
though, wasn't there a recent auction that brought $400 US for a few?.
 
I actually saw a antique show that included a segment on transistors, but
the article in question was a hanging framed piece that showed the
progression of transistors from tubes in the past to present (the present
being around 1980). The problem was that it was appraised at 50.00, and the
framing, and artwork would probably run you about that amount, unless you
did it in Japan, and made them 100 at a time.
