don't worry i work with Island dollars a lot, they are in thailand shooting and doing biz so a US check prossesor does the checks and sometimes they send them early and the date on the check is wrong just wait til the 3rd it will cash fine i had 1 or two like that
I will ask Marty to have the company look into it, because it does look strange. Basically it just got mailed too early, it is dated that way to prevent theft.
