I just bought a house from an older couple that had graciously left behind a lot of "goodies" that have been gathered up over the years. On of the said "goodies" is a box of 40 beautiful vintage Kentile vinyl asbestos floor tiles. One has been broken or roughly cut in half, but the rest look to be flawless. I have three small children & was wondering if these are safe to install or to even have around. If they are & I don't use them, would they be sellable on Ebay, etc., or are they "illegal". I'm sorry if these questions sound stupid...remember I'm a new homeowner & have lots to learn :o) Thank you!
