If it wasn't for US Scott #11's, I wouldn't nearly as far along as I am. I have 13 of them. In 1851 3 cents was the cost of mailing a letter and they must have made a gazillion of them. I have quite a few US Scott #26's as well. I guess the key is to find a stamp that was plentiful for several years. Presently, you have many different stamps to pay for postage, but back in the day, you usually only had one option, unless you wanted to overpay.
Filled three more dates with a Scott #681 for March 2nd; a Scott #792 for June 23rd and a Scott #470 for July 31st. That gives me 120 different dates covered with only 246 more to go. The March 2nd & June 23rd stamps have awesome centering and would have a nice place in my U.S. album if they weren't cancelled with a legible date. Two different railroad stations in New York City are covered as well; Grand Central Station and Madison Square Station.
Filled three more dates with a Scott #C4 for February 1st; a Scott #452 for October 28th and a Scott #773 (with awesome centering) for December 17th. That gives me 123 different dates covered with only 243 more to go.
Filled two more dates with a Scott #769a for June 29th and a Scott #628 for November 21st. That gives me 125 different dates covered with only 241 more to go. I don't know what the difference between a Scott #769 & #769a is. I don't have a Scott Catalog and I couldn't find anything on the net to differentiate them. Anyone know?
Yes 769 is a pane of 6 and 769a is a single stamp. Not sure why they give it two different cat numbers. But that was Scott cat from 1975, now they have new numbers 769 has a gutter in between them 751 were already cut apart so no gutter. and a special printing 756. A lot of numbers for the same stamp lol.
Filled two more dates with a Scott #657 for July 19th and a Scott #669 (Nebraska Overprint) for November 12th. That gives me 127 different dates covered with only 239 more to go.
Last two before I go on another shopping spree. I filled two more dates with a Scott #740 for April 22nd and a Scott #741 for December 21st. That gives me 129 different dates covered with only 237 more to go.
I filled one more date with a Scott #3830 for March 27th and found a replacement for May 22nd with a Scott #3054. That gives me 130 different dates covered with only 236 more to go.
Normally I'd say yes, a stamp is a stamp. That is a Revenue Stamp though and wasn't used for postal matters. If it was used for postal services, then you've got a very scarce find on your hands. I've stayed away from Revenue Stamps, even though I have quite a few, because they are almost always cancelled by date directly on the face of the stamp. That would be a shortcut for me to fill in a lot of dates in this set. However, I'm in no rush and am trying to fill it with stamps used for postal purposes.
