The 15c is on the rise...again.
It used to be that the only ones that broke $200 had a manual and a box...now I see one that broke $360 without a manual or a box, and even has a worn slipcase.
Extraordinary!
And then there is the 49G. What had been sold for $20 to $30 spiked to $40 to $60 for about a week, and now seems to be deflating like a leaky balloon.
"Pricing" for antique calculators seems to be nothing if not reliably volatile. I noticed the same basic tendency 10 years ago, but now the prices are higher :-/
We should start a spoof radio show--like "Marketplace" on public radio. When we "do the numbers" we can really do them!
