Here is another anecdotal example of the 2014 surge in prices for pre-1935 Beistle, Dennison and Gibson items. This mechanical tally made by Dennison beginning in 1928 typically trades for ~$65. This surge is definitely a recent phenomenon. An identical tally was offered on Ebay several months ago with an opening bid of ~$45 and it failed to garner a single bid.
