I think I finally found one lithographed yesterday, (confirmed based on the perforations) but I'm uncertain. The edges and numerals are clean, but the bust looks composed of small dots. Is this typical of Machins? I've found scans showing the difference between the numerals in photo. and litho. machins on the Internet, but nothing showing a close up of the differences in the bust. I think I'm going to go blind looking at these through the magnifier... and I'm not even planning to keep any variations other than print type (i.e. phosphor tagging, etc)! 8) @Charlie, Keijo

We advise the collector to look either at the value borders or along the stamps outer color border. Photogravure stamps have a ragged edge where the color lines meet the non-color areas. Lithographed stamps have a more or less clean edge. In fact, in many Photogravure issues, where it is important for the specialist to determine whether a stamp was printed from top to bottom or bottom to top, ( or even left to right instead or right to left,) to decide which printing is being examined, we look along the outer edges with a magnifier and can see the difference in the way the raggety edge is formed. On Lithographed stamps the direction of printing can not be seen by examining the edges.
