Porter Counterfeit Detector. This is the equal
Porter Counterfeit Detector. This is the equal of the finest example of this rare counterfeit detector that we have seen. The wood case is flawless but for a few minor surface scratches, the glass is perfect and original, and every knob, screw and moving slide is original and without damage or wear. This detector operated on the basis of placing a genuine note on one sliding panel and a suspected counterfeit on the other, and then by manipulating the panels, the notes could be drawn into line on the alphanumeric graph, and the position of various elements could be compared. In short, it was pretty much useless. But what a fancy package. Included with this detector is the original instruction booklet. Over the years, we've seen eight of these detectors, only one other of which is as well preserved as this beautiful piece. The original glass is etched with the graph lines. Most Porters have had their glass broken and replaced at some point, but not this one. This detector contains two genuine modern $1 Bills for demonstration purposes. The exact date on which these were manufactured is a matter of conjecture, but materials and craftsmanship seem to indicate late '20s or early '30s. The instruction sheet with this detector has an overprint export-agent name and address, which indicates that these were still being sold in the 1940's, as the agent's San Francisco address includes the two-digit postal-zone number, which came into use in May of 1943. <BR><BR><B>Important notice:</B> Heritage usually auctions material at the rate of 200-250 lots per hour. On some occasions eBay Live bid software or the Internet may not be able to keep up with the pace of the auction. We recommend placing a realistic absentee bid now as insurance to avoid disappointment. Occasionally the auctioneer may eliminate or reject an eBay Live bid, and the auctioneer may also reopen a lot after the close of the eBay live bidding (usually because we missed an audience bid), and may reject your bid even if it shows you as the winning bidder. By bidding via eBay Live, you agree that Heritage may award the lot to another bidder at its sole discretion under the circumstances described above or any other reasonable circumstances. Since eBay bids are not shown to us until we open the lot on the floor, we treat those bids just like floor bids. In most cases the floor responds before the eBay bid is presented to us, due to Internet lag time, so for consistency we have made it a policy that floor bids are always considered first over tie eBay live bids. Also please note that all Heritage lots purchased through eBay Live carry a 20% Buyer's Premium. Please make sure you read the Terms and Conditions before you bid. <BR><BR><B>IMPORTANT ANNOUNCEMENT ABOUT RESERVES:</B> Heritage now divulges all reserves on its web site 7 days before every auction. If you want to know whether the reserve on this lot has been met, and if not, what the reserve amount is, please visit this lot page on the HeritageCoin.com web site, or email: bid@HeritageGalleries.com
