Corn Snake genes are a simple, you need to understand how they work if you want to breed for anything cool.
We all know that genes are the blueprint that living things are made from. In Corn Snake many "morphs" have popped up that will cause the snake to look different from a "normal" corn snake. These genes come in a set of two, one gene from the mother, one from the father. If both are the same it's called Homozygous, if they two are different it's called Heterozygous. Homo and Het. The "Normal" gene is a dominant and will always determine what the snake looks like. A snake that is Homo for a Morph will be altered to look different from a Normal, a snake that is Homo for Normal or only Het for a Morph will look normal. So your Amel is Homo for Amelanistic (the Morph that stops the development of black pigment). If you're snake was Het for Amel it would look normal.
A snake that is Homo for two Morphs will show both a combination of the two. A Snow corn (amel + anery) has no black (from amel) and no red (from anery) it still will get yellow and pink. Now if you had an Anery and an Amel and breed the two you would get Normal babies het for Amel and Anery. Because each parent would be contributing only one gene an Anery that still has the gene to produce black would pass that one gene to it's offspring. The Amel would in turn pass one gene to make red. The result would be babies that are het for both Morphs but would look Normal because the normal gene is dominant. Now if you breed those babies back to each there is a 50% chance to pass on any gene they are Het for. two snakes Het for anery would produce about 1/4 babies Homo for Anery, 2/4 Het for anery and 1/4 Homo for Normal.
So, unless you Amel is Het for another Morph it will only be able to produce Normal het Amel or Homo Amel offspring. Amel is common enough that it's not worth much more than a Normal.
It is likely that your Amel is Het for another Morph, not many people breed to get Amels but try to get fancy double and triple morphs that use Amel like Butter (Homo Amel + Homo Caramel) or the above mentioned Avalanche (Homo Amel + Homo Anery + Homo Bloodred) so if the breeder was trying to produce Butter or Avalanche you're snake could be Het for Caramel or Bloodred.
With a Het gene it's impossible to tell if it's there unless you prove it by breeding to another Het or Homo and getting offspring Homo for the Morph.
There are a few exceptions, Ultra is a strange gene that actually pairs up with Amel. This forms a Morph called Ultramel, and Ultramel has one Amel and one Ultra gene in a paired, this means there is no such thing as Homo Ultramel but because there is no room for a normal gene in the pair it takes on the look of an Ultra and Amel.
Another odd exception is that snakes Het for bloodred sometimes show some of the Bloodred look like diffused sides or no belly pattern.
So to conclude this all. An Amel Corn is a very nice looking snake but not worth much money because of how common it is and would take at least two generations to combine with something to make a rare snake, it would take a mate with less common genes, two generations and about 6 years to make snakes that are worth more money.
