the yellows were not made in the reissue.
prices for new old stock has plummeted because now you can buy a new one for around 40.
i would say, fifty is a good price, or check ebay and find the lowest price for a brand new one plus shipping and add ten dollars.
if that is not satisfying, i would say sell it for how much you bought it for, minus the used condition it is in now. hopefully someone will bite.
