Question I have some very rare100 year old USA printed stamp stationery in a stamp book .They have been cut around the shape of the printing imaige leaving no margin I note that stamp labels are described as cut square does that mean my stamps are worthless..?
Your items are CTS, cut to shape. This was popular for a short time. Common material CTS has no value but then common material in a nice large full corner has little value. Extremely valuable material CTS is popular as space fillers and may reach as much as 5% of the retail value of a proper cut square and lesser value scarce and rare material typically sells at 1-2%. The value of stamps varies with the centering and the value of a cut square varies with the size with extra value if the both the back and side flap are retained.
