HP-31e



#2

I have just come across a HP-31e in the original box with manuals and power supply. I put two AA batteries in it and it works. However, the 9 and . do not have the click feeling on the button, but still work. It has the metal battery cage and plastic clip. Just wondering what it is worth? Thanks.


#3

One way you may find an indication as to how much your HP-31e worth is to visit eBay.com. You may find many HP calculators in this auction site.


#4

I have checked the auctions. Only found HP-35's which I have from 1972. I have the original shipping box, plastic storage box, manual, leather case, etc. It all works but the battery has been replaced with different ones.

The HP-31e is not listed in any auction. It's either not readily available, difficult to find or no one cares.


#5

The collectors corner (click on prices on the main page) has some info. The HP-31e does turn up for sale less than the HP-35 but the HP-35 is considered more significant


#6

thanks for the feedback. I'll look at collectors corner. I was also considering putting the HP-35 on ebay but it is hard to part with it. Ken

#7

Hi Ken,

I bought a 31E on ebay about a month ago and paid around $100. It came with a charger and was in very good condition, but no manuals or box.

It's the only one that I've seen on ebay in a long time.

-Katie

There is a HP-31e now on ebay and is currently at 118 with 5 days to go. I am kind of surprised. Thanks for you feedback , it is appreciated.
