At this point there is only very minimal interest in collecting older electric adding machine, even less than typewriters. At auction examples like this often fail to get bids or sell for less than $30.00 in most cases.

Some people get a really unrealistic idea of value because they see these things as being "Antiques" and list them with crazy prices on Ebay, Craigslist and other online sources. What they go for at auction really gives you the best idea of the market. If you see 200 comparable machines sell at auction for under $30.00 in the last year and see the same machine listed retail for $300.00 you know something is out of whack ;~)
