Would you buy it?

Me and my kid do treasure hunting in flea markets, we do 3 weekly and now we found this collection, it has about 50 cards. Most from 2007-2008 but found these two. They wanted $25 for the whole. The Mega Gengar had white corners and mewtwo had a bent corner.

Would you say $25 is a valid price?
