Ice age Plains

So I'm seeing a certains plains from ice age with a mid price of about $75....and a low of $0.40. On peoples tradelist. I did some research and I have found nothing stating why this land is so much. On SCG it's $0.49. TCG $0.40....$75...$225. I do have it on my inventory but not my tradelist cause I'm pretty sure it's a really big error. If not, HOORAY!!! lol. Any body have any answers or guesses?
