VAM - Two questions - Are the changes/variations were made by the designer or not ? Why the changes
VAM refers to different varieties of Morgan and Peace Dollars. 
The Morgan Dollar is named after its designer, George T. Morgan, who designed the obverse and reverse of the coin.
VAM - Are the changes/variations were made by the designer or not ?
Why the changes have not been reported for many years before their discovery ?

Significant changes - My example:

They are identifiable varieties due to (often insignificant) variation in the dies used to produce the coins. It's really the variability of the manufacturing process that results in the differnt VAM's, and with a few exceptions, NOT the result of intentional design changes.

Instead, they were most often the result of mistakes by Mint workers, improperly made dies, poorly aligned dies, etc... the kind of things you can file under the heading of "stuff happens".

That particular VAM, by the way, is excessively common.
<< <i>Mint worker may have dropped something on the reverse die, or dinged it against something to create the "spit" feature.

Yeah....I kind of doubt George Morgan was sitting around the office one morning, and decided, "Hey! You know what would be fun? What if we made the eagle spit! Collectors would be entertained for YEARS with that...." Jolly Joker, that George!
Nope. Just a die variation. Same holds for Overton numbers for Bust Halves, or Sheldon numbers for Large Cents, or Valentine numbers....basically every list of die varieties for coinage that exist.
If the die difference can be identified, and is repeated with every coin made with that die, then you have a variety that someone has either identified, or someday someone will.
They are fun. But they are at their very heart, either just mistakes or slight variations inherent in the process of creating dies, using the technology and techniques that existed at the time.
