so i found this old piano in an antique shop and tried playing it. i'm not really an expert in the piano or anything but i do enjoy playing it once in a while. the keys were already yellow (it IS in an antique shop) but they're really soft to the touch and sounded decent. would it be wise to , like, buy it? would it not, like, crumble after a few years? by the way, the owner could not give me the exact age of the piano, said it just was dropped off to her by a customer. soooo, what do you think?

Yup! You can sell this piano & don't get worried about it. If it is right condition people will take it.
