Try to remove the 'fuzz' with a little rubbing alcohol on a cloth but don't rub to vigorously and take care not to damage anything, normally green deposits are not a good sign as this could indicate damage from leaking battery acid.
Year circa 1975, others might tell you with more accuracy.
(
Update: Just noticed the date sticker on the module: Jan '76)
Value circa $80, although prices fluctuate considerably.
BTW: Your caps lock key appears to be stuck on, lower case is better, upper case is considered to be SHOUTING.
