Some further information, for LP collectors. The key to knowing Mercury pressings is the deadwax, 
not necessarily the label color.

1. in the MONO era, 1951-57, the first edition MG series will almost always have a "MF" and number. 
This indicates Miller cutterhead, Fine Sound Studios. On many of them, maybe all of them, there is 
an "I" indicating pressed at RCA Indianapolis. The number after MF indicates the specific 

2. in the EARLY STEREO era, 1958 to about 1962, there will be a "FR" for Fine Recording, usually a 
"P" followed by two numbers, indicating a George Piros cut and the lathe number and cutterhead 
number. Anything pressed by RCA will have an "I" and the stamper numbers such as "A1."

3. in the PHILIPS era, from about 1963 onward (might be earlier), there will be "RFR", which 
indicates Fine Recording cut, Richmond pressing. The "P" numbers will be there, but no RCA markings. 
Some of these are better than others. The Richmond plant, even when the Mercury Living Presence 
staff was riding herd on quality control, was incapable of consistently high quality output in the 
league of RCA.

4. most MONO cuts from the STEREO era, circa 1958-1965, will carry the "JJ" mark, meaning they were 
mastered by John Johnson.  Keep in mind that mono LPs outsold stereo until retailers stopped 
carrying double inventory (see John Eargle's article in the JAES about stereo-mono compatibility, 
which includes RIAA sales figures from the start of the stereo era through the mid-60's).

In today's collector market, the most coveted Mercury Living Presence LPs are the original early 
stereo records, those pressed at RCA. The first editions usually have a glossy laminate on a true 
lithographed cover, and include a strip of color graphics on the back. Later versions, manufactured 
at Richmond, don't have the glossy laminate, sometimes don't have color on the back, and are made of 
lighter cardboard. I always tell LP nuts, avoid any later pressings, definitely avoid any Wing 
reissues of any MLP content, and consider carefully if you want any vinyl version of something 
released on CD. My mother always said, and I very much agree, that the digital releases are closer 
in sound to the master tapes than the original LPs. This is due to the fact that LP cutting 
inherently imposes limits on frequency response and dynamics, the LP release medium has a very 
audible noise floor, which reduces net s/n quite a bit, and early stereo cutting was an imperfect 
craft. I do agree with some of the LP diehards that the artifact of the early LPs is much more 
beautiful presentation than the CDs, despite the carefully prepared and edited booklet notes in the 
original 1990s CD issues. So I tell people, if you can get your favorite material in original LP 
format at a bargain price, frame the cover.

But listen to the CD if you want to hear all the splendor of the performance and recording. There 
are a few exceptions to this statement, cases where the source tape for the original LP was superior 
(because the first-generation tape was lost or known destroyed by the time the CDs were made). And, 
to my ears, Bernie Grundman's LP cuts, directly from my mother's original playback gear and 
first-generation 3-track sources, released by Classic Records in the mid-90's, are the best Mercury 
LPs. Cutting technology had advanced quite a bit in 35 years, and Bernie is a real ace. He turned 
off all the dynamics-limiting automation and cut it old-school, with my mother reading ahead in the 
scores and signalling dynamics changes just like she had done with George Piros for the original 
LPs. Combine Bernie's great cuts with RTI's superior pressing and really great LPs resulted.
