UO Second Age

Hi guys. Quick question here.

A player was nice enough to give me a treasure map to sell.

Is there any way to determine what level a treasure map is so I can sell it appropriately? Thank you for any advice.

Not without knowing which monster dropped it, no.

you can try decode on a 0 cart char, depending on the message you get it's either lv1 or lv2-5

if it's level 1 you will get a message "you fail to decode the map", if it's lv2-5 you will get a message something to the effect of "this map is too difficult for you to decode"
