Should I have stamps certified???
I am new to the stamp forum and have a few U. S commemortive stamp that relate to my U. S. Classic Silver and Gold commemoratives. Most of them are from the early 1900's and were issue at or about the same time as the commemorative coin. When I acquired these stamps I issisted that they were mint, unused, original glue and never hinged and some were rather expensive at the time. The stamps include the 5 Louisiana Purchase stamps issued in 1903-4, the 4 Panama Pacific issues in 1915, some of the small valued Columbian stamps from 1892, Pilgrim stamps from 1920, Hugeunots stamps from 1920, U. S. sequicentennial stamps from 1926, and various state centennial stamps from the twenties and thirties. Would it be worth the time and expense to get these stamps graded by one of the third party services and if so which one is the best? My game is coins so I am a novice when it comes to stamps.
