Just wanted to pop in and say thanks for the great information. I saw a story this morning about a factory sealed Legend of Zelda that was going for a huge amount of money which made me think of my collection from the 80's. I still have the NES and play it every now and then with the kids but a couple of years ago I sold most of the collection to a retro game store in Oshkosh, WI. I probably lost out some money by doing so, especially for a Super Mario box and 5 screw cart that was in great condition (early 1987 according to this guide: https://www.watagames.com/learn/blog/post/nes-black-box-variant-guide/), but went to what I think was a good 'home'.
But one of the games I kept was my Legend of Zelda (along with a few others and some SNES ones). Looking at your great research, seems like I have Box 1, Cart 1, and Manual 2. It is CIB but the manual and map (which some grade schooler marked up, pfft) are not in great condition. I wonder if they are worth anything...
