Hello so I have a few Japanese MTG cards from the year 2000. Among them is a Mountain #344 (from Invasion) illustrated by Jeff Miracola in foil. The English version's value is 1.49$ and I've read that due to rarity Japanese versions cost up to double the price.
I also can't find prices for other cards that I have that probably don't have much value which are some Dragon Quest Card Game cards including a foil one, some Monster Collection Trading Card Game cards, and some Kikaider The Animation cards. I would appreciate any orientation into finding if they have any value other than nostalgic.
PS: Just to clarify all those cards are in japanese
