Need Help With Mexico Stamps

I bought a collection of U.S stamps from ebay and the seller put in some extra pages of other country's which was nice, but I only have U.S books and know idea what they are or their value. I tryed looking for an online cataloge for central/south america but couldn't find one so i'm asking for some help.

Starting left to right; {C65 or C133 or C170, different Watermarks); (C68 or C80/81, If the bottom margin has the phrase "Talleres de Imp. d Est. y Valores-Mexico" is a C81, C68 is wmk, C80 is not); (C718/a or 732/a or 787 or 841, I believe it is 731/731a difference between wmk/unwmk, "Talleres de Imp. d Est. y Valores-Mexico" I see at the bottom of the stamp); (759); (I believe it is 729/a, difference between wmk/unwmk, "Talleres de Imp. d Est. y Valores-Mexico") That the 1st line!

Second row: (790 or 846, unwmk/wmk); (733 or 788 or 844, 733 "Talleres de Imp. d Est. y Valores-Mexico", 788 or 844 have different wmks); (730 or 785 or 838, 730 "Talleres de Imp. d Est. y Valores-Mexico", 785 or 838 have different wmks); (No ID); (RA14); (714 or 714a, gray green/olive green); (711).
That's line 2!

Hi razersedge,

warrehouse did a good job getting you started on these. All the stamps are in the Scott catalog. The stamps you show seem to be ones that have minimal value. However, as warrehouse states, the perforations, watermark and size are crucial to uniquely identifying the stamps.

If you email me at jerrybemail-stamps "at" yahoo "dot" com I will send you a table that will simplify identifying them. Please put SCF-Mexico in header.

I guessed they were in Scott but I only have a us specialised and I was looking for Cheepish world wide on ebay but couldn't find one, I was hopeing it was a little easyer than it appears to be to Id them, I guessed there wasn't much value but the revenue looked a little unusual and I try to make the most out of my 99p wins lol. But there was a lot of other countrys in there
