This idea that will follow is just something that I am curious about. Is it possible that there could be two coins, that could have a combined variety? EX: a matron head large cent has a leaf on the reverse that is of a similar relief to a leaf on a Morgan dollar that is also on the reverse, in a similar lcoation , that has very similar characteristics to make some sort of Newcome vam variety? As many of you may be able to tell, I am very unfailar with varieties, but I am just kind - of curious.

There's no such thing as a "combined variety." Newcomb is for 1816-57 large cents, period. VAM is for Morgan and Peace dollars, period. Both terms refer to the catalog of die marriages for their respective types. I hear and read variations of "this coin has a VAM on it" frequently. That can only make sense if there is a Morgan or Peace dollar physically sitting on the coin in question. A feature like a doubled die or repunched mintmark can be a characteristic of a VAM, but it is not a VAM by itself.
The idea behind varieties, for both large cents and Morgan dollars, although they exist for all coins, is that a variety simply IDs a specific pairing of obverse and reverse dies. So in that sense the answer to your question is no, there are in general no combined varieties across different denominations. I say in general because there are cases where the wrong planchet was used in a set of dies, i.e. a dime planchet struck with cent dies, but most would consider that a straight error, not a new variety. A broader interpretation of your question is, are there common design elements across denominations. For instance, the letter and number punches were often used on multiple denominations of coins. So a $10 gold and a large cent could both have the same exact punch used for the letter T, or some other design element. This does not however make them combined varieties.
