My grandmother's glass lamps

My 81 year old grandmother passed away 13 years ago and due to a variety of factors my family is just starting to unpack her belongings. She was an avid glass collector with items from Blenko, Fenton, Viking, Gibson and numerous others. She always told me as a child not to sell her glassware because I had no idea of it's value. I have been trying to find an appraiser with no luck. I have been searching the internet but I have been unsuccessful in finding information about these items. The ornate lamp has an image of a colonial couple together and has gold trim. The other lamp is like a series of paperweights with a glass bottom. It is very heavy. I have a red one that is very similar but it is shorter and has a metal bottom. Any ideas about the type of glass this might be or the value? Any help would be great.
