what's the value of my pokemon cards How Can I Find Out If Are Worth Money whats my pokemon card worth

Looking for Miraidon ex prices and values

1 The Mind Stone - Cosmic Foil Variant $30,000 - $40,000 There are only 150 copies of the Cosmic Foil Mind Stone in existence, and just like the Soul Stone alternative, it's the most valuable and rarest card in the set by some distance

Beyond its monetary value, this card stands out as one of the most valuable offerings from Fusion Strike, and it holds a pivotal role in the widely embraced Mew VMAX deck

Im still miffed about party not being tied in with the set more significantly, but I love the dungeons and the dragons, so Im sure Ill find it in my heart to forgive this oversight.
