Hello..

This information might helpful for you.The "schermack stamps" are known in the postal history of the US. Joseph Schermack created the idea of producing the first practical stamp vending machine and he formed the Sanitary Postage Service. The public in that era were concern of tongue licking the back of stamps had bacteria was transmitting diseases. The public was learning about transmission of diseases and concern how diseases were being spread and ways to prevent it.
Schermack's company name was changed over the years a few times, from mail om-meter to the mail -o- meter. These stamps are popular with collectors.

There are ways to tell the different types of "Schermack" stamps with descriptions. The Type 1 has a seven hole punch marking. The Type 11 has a six hole marking. They are known on strips.(more than one stamp together. usually seen between the two stamps.) The type 111, is known as the "Hyphenhole" punch. There were 10 different denominations,years and color for these specific Hyphenhole punch stamps. In your scan it shows a Type 111 Schermack Hypenhole". For the specific 2 cent stamp "hyphenhole", they were known on the following: 1902 2 cent (Scott #320, and Scott 320a), 1908 2 cent Carmine( Scott #344), and the 1909 2 cent Lincoln (Scott 368- 2 and 3mm apart.)
Mail- o -meter stamps unused have been known to display for selling in certain US auctions. For example, Daniel F. Kelleher Auctions under postal history section to give you an idea what they look like in unused conditions. I do not know if Corinphila Auktionen in Zurich, the oldest stamp auction house in Switzerland, have displayed any of them at all for their auctions.
