Some U.s Stamps, Any Advice Please?

I have some stamps here... I tried my best at identifying them, but apparently there are so many similar stamps from different year releases that I can't make out which one is which.

Some appear to be pretty valuable even when they are used, so please.

Could I get some professional opinions? :)

Most are fairly common. The 2 cent red coil (straight on both sides might be a Scott #487 or 488 worth a couple of dollars. The far right 1 cent green stamp is worth checking into. It appears to be a perforation 10 on the top and bottom with perforation 11 on both sides. If it is, it might be a Scott #424b which is a very desirable stamp with a high value. Please note that I said "might be".

Correction, I should have said "might be" Scott #498g for the 1 cent green stamp with perforation 11 on the sides. One problem is that my catalog indicates that a #498g has a perforation 10 on the top or bottom, not both top and bottom. There is also a possibility that it "might be" a Scott #424b which has a perforation 12 on the two sides.

I am 90% assured that I will most likely NOT find a stamp that will make me rich in these books, but i'm still going to hope. So don't worry about me getting disappointed or anything, I follow reason.

And thank you for the good advice.

By the way, does the number 8-13 or whatever it is. In this case perforation 10 and 11 like you mentioned. What does that number indicate? The number of holes made(supposed to be) or the number or jags that are on the side of the stamp?

Perforations are the round holes and the number (for example: perforation 10) refers to how many holes there are in a given measurement. Off hand I forget the measurement but it is usually millimeters rather than inches. Perforation gauges for determining the number of holes are available at most stamp shops. The cheaper versions are not very reliable.

After I posted the info on a possible identification I recalled a 1 cent Washington that was much more common than the two possibilities I have already mentioned. This new possiblity is a Scott #542 which as used is worth $1-2 and unused is approximately $5 and up depending on condition. It is distinguishable by measuring the width and/or height of the printed area which is called a "frame". The better clear plastic perforation gauges also have measurements in increments of millimeters to check the frame size. A very helpful website is www.1847USA.com The home page has a "WASHINGTON FRANKLIN WORKSHEETS" link. Click on "1c" under "Washington" to help you with your stamp.

Just to back up quigngt it is a 542 rotary press 10x11 unwatermarked, the centering of that stamp is normal for that stamp and
The 8c is a 414 single line watermark perf 12 and is the most valuable of the bunch so far
The 2c coil could be the money stamp though depending if it is a flat plate or a rotary and if it has a watermark or not, if it is a flat plate it is a 442 type 1, if it is a rotary with a watermark it is a 449 type 1, if it is a rotary no watermark it is a 487 type 2 but it is defenently a type 1 / 2 it looks to me like a type 1 (but I've been wrong before) which will make it a 442/ 449 and the way to find if it is a rotary or flat is to measure the design if the stamp is 22.50 high by 19 wide it is a rotary if it is 19 wide by 22 high it is a flat plate but the really easy way is to compare the design sizes of the 8c which is a flat plate and the 2c if they are the same it flat if the design on the 2c is slightly bigger then it is a rotary

The first 2c looks to be a 634
The first 1c could be a 552 or 594 or 596 depending on the design size ( flat/ rotary) 552 is 19x22 flat plate, 594 is 19.75 x 22.25 rotary coil waste, 596 is 19x 22.75 rotary sheet waste it is most Likly just a plain old normal 552 but it is worth checking
The 3G is a 555
The last 2c looks to me like a 279bf but it is not easy with the scan but it looks to be type 4 carmine

If you are interested in a great resource book that will help you whittle down the possibilities with those stamps, Micarelli put out a great book helping identify the early difficult stamps.
