Base Set triangle packs

Hi. I was at a chess tournament. And saw they had some Packs for sale. And they had the Base Set Triangle Packs. They had 11 of them. My friend bought 3. He opened on and gave me one. He then bought another later on. I also bought two others. I would have bought the rest but I didn’t want to take the chance. I didn’t know if they were fake or not. But I got them for $4 a piece.

  1. What is the value of them?

  2. About how many were made.

Should answer number one.
