dont listen to these morons, half dont have a fully functioning brain and half are envious that you have made what seems to be a profitable investment
how much did you pay for it? 10$? its now worth 130$ so already you are making a crazy profit on it.
if 130$ is important to you sell it now, if its not, then leave it were it is, take care of it, keep it away from sunlight or a heat source, keep it straight up, not lying down because that damages the grooves, and for gods sake bring it up from the basement, too much moisture down there
keep it in good condition and it will more likely increase in value as time goes by, especially as eminems career continues being fruitful, dont listen to these morons, eminems been a successful musician for 15 years and these fools acting like he is a one hit wonder, the man is a hall of famer
also with usage and wear and tear the number of records remaining will keep going down, wait till you have the only one
or buy them all now and destroy them
