You could say that linoleum feels a bit waxy to the touch, but you will also not notice a very glossy finish unless the floor has been waxed after installation. There are vinyl patterns that look an awful lot like real linoleum as well, so if you want the best way to tell your floor's make-up, pull-out your refrigerator or stove, or pull-off a piece of base in a closet, and remove a very small piece of the flooring. Usually around the edges it won't be perfectly adhered anyway. Look at the backing of the product. If you can see a mesh backing that looks like a carpet backing, it's linoleum. If it has a gray felt backing or is solid vinyl all the way through, it's vinyl.
