Morgan ?'s Paf Or Saf?

Can someone please explain rev of 79?

thank you. I've been here 2 days so I'm a baby so to speak.

correct, Rev of 79 is supposed to be on any date 79 or above. Some 1878 morgans had the reverse of 79 and there are some dates up to 1880 that have the reverse of 78 and that is a main feature of their VAM attributes

i type to slow

On the 1896 P did they use matchig dies, if not what dies did they use? Is this a proper question for this forum. I'm so confused.

What is it that gives the coin value? Is it the number of coin struck, Mint they were struck at, or the dies or is it the condition? What should I look for when buying a coin?

Yes this is the fundamentals of the coining process...
2 dies, OBV and REV....But for morgans one must remember the dies represent the intended image or portrait so to speak...
While the first original Obverse of ANA's face remains the same with minor changes, the REV features were changed due to minting issues...
The big book shows (3)type I,II and III Obverse's in which these features will be found on the Obverse dies(and coins)...
While the Reverse coins had many more changes in 1878, things like 8TF, 8 tail feathers, 7TF 7/8 TF, slanted arrow feather, parallel feathers are a few of them....Its by these features we identify the die types and marriages to attribute these years...As noted some of these dies were also used in other years....1878 is a tuff bird to figure out until you figure out and recognize these points.. but it does get much easier......I should note, while these in general are the basic die types, within the 1878 8TF series there were many many more Different reverse types ...This only an basic fundamental post so you get the idea of die types..not meant to be "ALL encompassing". one needs the book to see and study them and learn why there were so many.. ...It does however get much easier after that...
