Picture attached. I have two of these. Mercadian Masques, Plains (non-foil), card numbers 331 and 333. Obviously foreign, but what are they?

After some looking online, I found a picture of a Japanese Plains; it had different symbols than my two. That pretty much leaves Korean and Chinese, but I can't seem to find an example of either version online.

Also, if anyone knows what they're worth (guestimate), I'd be happy to know that as well.

I am not well-versed in the languages in question, but that appears to be Chinese.

Edit: Yep, I found a Zendikar Plain in chinese, same characters. ( http://www.mtgmintcard.com/images/products/Magic-the-Gathering/MTG-ZEN/285533/PLAINS-233.jpg )

It does indeed have matching characters. Thanks for looking that up!

I'm not sure what they are worth; anyone have any clue?
