"Hopefully an unscrupulous individual does not buy the material and resell it as real."
I know you don't intend this to be funny, rodgcam, but that is of course what is done all the time, especially with these early Japanese stamps. I'd guess waaay more than half of the Japanese earlies sold today are forgeries. Many were made for the so-called "tourist trade" at the turn of the last century and were mounted on sheets of paper as souvenirs of Japan. They're all over the place now so that it's actually difficult to find genuine early Japan. At times it seems as if the Japanese government flooded the market with these early stamps when the truth is a great number of them had nothing to do with the government. But at least they fill spaces in the album, I suppose. The Int'l Society for Japanese Philately sells a great booklet which describes in detail the fakes and forgeries of these early Japanese stamps. You don't really need "sample" forgeries if you consult that booklet. After awhile, a forged or fake stamp just "doesn't look right".
