Please elaborate on that.
Thanks
So the matrix is a series of alphanumeric codes that you will see at the end of an LP. Depending on what that code is, it can be traced to its origin. A first pressing will have a certain coding and be of higher value. A stereo/mono pressing will have another coding. The plant at which a first pressing, whether stereo or mono, in a particular country will have its own code. For example, The Beatles were released on Parlophone in the UK, but on Capitol in the US before they formed their own record company, Apple Records in 1968 (For Sale Catalogue and country snapshot). If you the see the screenshot (Beatles Top and Bottom) which has the two Beatles albums on top and bottom, you will discern that the "For Sale" LP is pressed in Japan, 1976 and issued by Apple, (Rohit For Sale and For Sale Matrices) so has to be a reissue. The Help! album is released on Capitol, hence a US pressing and issued in 1965.
In the same album in different countries and/or different years of releases there tend to be be subtle and obvious differences. There might be additions/omissions to the liner notes, credits, track listing etc. See the Sonny Rollins Saxophone Colossus LP valuation a first pressing in mono issued by Prestige is worth over 1800 Euro and I own a Japanese pressing in mono on Prestige which is worth about 50 Euro and another pressing of the same that is worth next to nothing because it was pressed using a digital source. The pictures attached are named accordingly. Hope they are uploaded that way.
Depending on the origin, pressing AND condition of sleeve and media, etc etc etc., the suggested valuation is arrived at by the last highest/median/lowest price it was sold at, thus helping you to value your collection.
See the Bill Evans pic for how a matrix number looks like. I think someone had posted a wonderful article on the forum on how different labels write these numbers. I'll try and post that link here. I hope this helps.
