The one piece marked LODGE 5H12 is called the Holiday muffin pan in the catalogs. It was available in the 1990's. Now that you have that one, you need to find the 6SM2 Snowman pan. I have both of these pans, and they make great muffins. As for price, they are all over the place, anywhere from $8-$35. I picked up both mine on the low end. These are very heavy pans, but like I say, they bake very well.
When it comes to cornstick pans like the 9-section one you have, I tell people that the value in them is giving them as a gift. They have no value to me no matter the maker. I'd just as soon shingle my roof with them.
I would have to see photos of the bottoms of the other 2 pans; since I've seen Chinese knock-offs of them. Even then, they are recent pans and don't bring much.
The #10 skillet is a BSR, but I can't see if it has "Made In USA" on the bottom. Still, they can be found around for less then $20.
