What Would You Do with a Sealed, 1st Press Miles Davis "Kind of Blue"?

If I can see mold on the,LP, it  is not sealed.

 I have several sealed lp’s From the 80’s

my favorite is a sealed copy of Venom’s Welcome to hell LP!
original copy.  There’s a small chance it’s. The purple copy, which it’s worth a lot.

 I. Have about 15-20 sealed metal LPs from the 80’s

i was in Tampa a long time ago, when aces records was still. Open, I mkxed out my discover card, as they were slowly closing,
i bought 500$ of records, all 80’s metal records, they all remain sealed to this day, as I had most of those already on LP or cd.

i enjoy looking at. Them.

 I love my sealed copy of Exodus bonded by blood, on torrid!
among so mnay others.

keep it sealed if it is truly sealed.
all mine are unopened and still sealed. As new.

if it’s open, it’s not sealed.

I suspect that the manufacturer or LP records sellers in the 60s or earlier sealed some records into inner plastic bags in order to conceal their defects (warps or mold spots, which is the case here). A year ago I came across an LP by Miles Davis (not KOB, a later title) with sealed inner bag. I was about to purchase it - the outer jacket was opened but the record itself was sealed as described).

I didn't purchase it then, but later on, the seller opened it and the record was warped and that warp could not be cured by a vinyl flattening machine.

I meant "or sellers"...

Not a big deal and it’s value will not have any effect on your net worth.  I would open it, clean it of mold and other debris and enjoy.  Tell your grandchildren about your find.
Enjoy it.
