Nice selection of back of the book material.
Your first scan (1 Pack Playing Cards) is probably an RF27 (perf. 10) issued in 1940. Minimum catalog value, though. (There were other varieties (perf. 11 and perf. 10.5 x 11) which command higher prices, but are much scarcer.)
Your second scan is quite interesting as it relates to the Federal Fuel Administration enacted during World War I. Here's a Wiki link to its history:
http://en.wikipedia.org/wiki/Federa...ministrationThese stamps are not listed in the standard Scott catalog, however, still an interesting example dating to back to the early 20th century. I did find this quote from an old April 12, 1919 edition of Meekel's Weekly Stamp News that mentioned the stamp as follows:
Quote:
Many months back, we made mention of the fact that the Federal Fuel Administration of Philadelphia had issued Fuel stamps of the value of one ton to twenty-five tons and these were sold to the coal dealers, at the rate of two cents per ton. The dealers were required to use them in connection with each sale of coal. The money so obtained helped to defray the expenses of the Fuel Administration. While these had no official recognition they were collected by some and classed as local revenues. We wish to mention that when the Fuel Administrations recently closed its offices considerable quantities of remainders were distributed and as a result these fall in the Seebeck class.
Your Third scan is a US Special Delivery Stamp Scott #E19 (perf. 11 x 10.5). Value is minimum catalog.
Your Fourth scan is a NY State Revenue stamp. Again, this is not listed in Scott catalog but there are special reference catalogs available for many of these. Unfortunately, they can be quite expensive. I have many examples of the type shown and don't believe they command anything more than minimal catalog value and since they were issued by many different states, it's really getting into a specialty that not all collectors may have interest in.
The final scans are from a series of Proprietary Stamps issued in 1898. You show the 5/8 cent (RB23) and 1/4 cent (RB21) varieties. In used condition, both show minimum catalog value.
Nothing too valuable, but still a nice assortment to begin a collection.
