Scott 387 is a 1¢ green stamp featuring the profile of Benjamin Franklin. This stamp was issued on November 1, 1910, and is notable for its single line USPS watermark, a design intended to enhance both uniformity and strength in the paper used for the stamps. The printing method for this stamp was flat plate, and it features perforations measured at 12 vertically. A total of 3,794,000 copies were issued, making it uncommon but not rare. The earliest documented use of this stamp was on November 5, 1910. The Scott 387 is particularly known for its poor centering, which has affected its valuation and desirability among collectors. Generally, higher quality specimens, especially those in mint condition or with no postmark, have seen significant appreciation, further reflecting market trends in philately. The design incorporates 12 gauge perforations, which were not very successful as they made the stamps prone to breaking apart, particularly since these coils were primarily used in vending machines and were later replaced by a different perforation design (8.5). Recently, notable sales have displayed the stamp's value with individual pieces fetching between $20 to $175, while pairs have reached up to $1,300. The guide line pair version is particularly sought after due to its rarity and higher valuation.
