This is pure art beyond what it is; everything is beautiful, this collection of your mom certainly has value; I recommend using Google Lens so you can find exactly these models and you can check their costs, open the app, focus on each object with the phone and hit search and you will find the pages specialized in this type of items, I did it with some of your photos and it was interesting what I saw.
My grandmother used to collect glassware, it was crazy what she had and my aunts inherited it and sold it all before moving. What you show us is too well taken care of and I don't doubt you will have problems selling them if you advertise them well (here you already did hehe)..... Greetings and have a great week, I loved reading you and seeing these great photos.... You Rockkk!!! 👍😎🔥❤️
