Ancient Mew Pokemon Card 2000s Pokemon Movie Promo

This is for ONE ancient mew Pokemon movie promo card. My grandma worked at a movie theater in the 2000s and they handed out these as promo cards for the 2000s pokemon movie, when the promo ended she took them home and they have sat in a box alone in the garage for 25 years labeled “fast food toys”. When I found them a few days ago they were sealed but I sadly opened these ones not knowing their worth, I instantly put them in these card holders. They are near perfect condition, no scratches or bends visible on any of the cards. If you would like a picture of a specific area or a picture in a specific way let me know. I have three photos on the last slide because I am making three separate listings for three separate cards and want to show that I have three separate cards and am not just using the one to make multiple listings. I had to take this one out of the sleeve thing to show the back since it was in two sleeves and one covered the back but I was really careful.
