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

4th lacquer from 1st master tape according to discogs. 

Try to find a sucker to pay you far, far too much for it.  P.T. Barnum was right you know.

I would invite a few friends over who can truly appreciate it, and listen to a piece of history. Ask them to bring over a few bottles of a 59 Bordeaux.

Sadly I am all out of 59s, but it takes a discerning palate to appreciate that the 59s are often better than the highly touted 61s. Wonder if the same holds true for LPs......  ;-)

You have an EARLY pressing, NOT a first pressing.

1D  /  1AD    

SD-1   1D  indicates this side was pressed from one of the first 4 pressing stampers sent to Columbia record plants

SD-2   1AD indicates this side was pressed from a MUCH LATER pressing stamper sent to Columbia record plants

Given the matrix information and difference between the 2 sides, I would suspect that your side 1 was pressed near the end of the useful life of this stamper and probably does not sound as good as true first pressing.

A first pressing of KOB would have matrix information for both sides showing some combination of 1A  1B  1C  1D....no higher.   

1E or 1F represents an early repressing of this title.

Columbia LPs of the period DID use thin clear sealed inner sleeves as described.  I have purchased several first and early pressing Columbia titles from this period with sealed inner sleeves.

These sleeves were not air tight, and the gauge of the material was very thin.  It is possible for mold spores to have settled on the LP surface, even though the inner sleeve is "sealed".

Value ?    Whatever someone would pay.   List it on EBAY with large clear pictures of the SEALED inner sleeve.   Last 2 SEALED inner sleeve copies sold for $400+

Thank you very much to all for your insights, comments and information.  I am inclined to open, play and keep this sealed early pressing, but am in no rush... surely there is a good, humorous medical or psychological term for such keeping of sealed LPs??? 😉
