The Fiestaware (bright colors that Nick likes) should have some value, there are lots of collectors of that.
The blue is really nice American Pattern Glass. I'll show it to Ellen later and see what she has to say. She collects some of that, but not in that color. The market has gone soft in the last few years. We go to the annual show here in Jacksonville, and there are fewer vendors and lower prices each year. The top collectible names still get good prices, but the secondary stuff isn't.
The simple china pattern looks to be Pfaltzgraf. It's good quality stuff, but like so many of us relics, not in high demand.
The cut glass looks real, but often you have to feel it to confirm.
We are kinda in the same boat. We have family stuff dating from the 1600's and no one in the family is interested, and the market value has pretty much evaporated. Our daughter took me aside once after her mother had been explaining in excruciating detail the history of some of the furniture she inherited and said "Let me know what I HAVE to keep".
Bob, I had those same plastic bricks. Looking at what is available from Lego now, its a wonder we didn't die of boredom. Between those, Lincoln Logs, and Erector Sets, we had a pretty rich childhood.
