It even happens IRL. There was a guy who was hesitating of a junk for junk trade due to $.15. This is in the uk where that's like 10p. In the end when I was home I checked and he was vastly underestimating my cards and overestimating his cards. This is why I'm loving deckbox. Makes it a lot easier.

Amen, cards aren't currency, they're only worth what people will hypothetically pay for them. Actual ££ is more valuable than cards anyway!!

Lorwyn thoughtseize is $47 whereas theros is $17 is this right?
