EBTQ -- $100 - $150
XBWR -- $100 -- the X is very interesting when it comes in the beginning or end of the string. X is used for 'extra', 'extreme', or as a retro (at the end of the string) symbol for "unkown quantity". I think, in general, many 'x' LLLL are under valued and there is an opportunity here for faster appreciation than with some of the other semi-premium and random bad letter combos.
