All 1000+ cards are Holographic Yu-Gi-Oh cards. I simply don't have the time to research them all individually and I would rather they go to someone who appreciates them. What I can tell you about them is what I was told.
The previous owner bought 8 different boxes to accumulate all these Holos. Also a lot were bought individually. There are 23 different types of Holographic cards.

The value of the entire collection here is into the thousands.
