500 albums in a basement flood--worth saving?

Hi--just had 6' high (relatively clean) water fill basement during recent hurricane/tropical storm. Lost everything down there including 500 albums: some late 60's rock, 70's & early 80's rock, some jazz and a few classical, most in pretty good shape prior to this. Couple of Original Master Recordings. No turntable at the moment. Insurance not covering.  Question: is it worth peeling/discarding album covers, buying 500 new sleeves, buying record cleaning machine (lots of time & labor), or just toss the lot?  Are they worth anything without the covers, just inner sleeves (what type are best, paper or plastic?)?  What is average value?  TIA.
