how to tell on first pressing vinyl releases

I started some flea market and ebay searches and am perplexed on how to tell if an album is a first pressing release or a later release.

Also are less than 180 gram re-releases decent quality (think jazz reissues in the $10-15 range from Acoustic Sounds)

I did luck out on a two eye Brubeck Time Out and what appear to be first issue Jose Feliciano and Joni Mitchell discs.

If they're expensive, they're original. Otherwise, you'll have to look at the album in person.

Congrats on your Jose Feliciano album.

Many records have codes stamped into the deadwax which enable you to determine whether it is a first, second, etc. issue.

For example, here is a link for Pink Floyd which will enable you to determine information regarding country, issue, release date, etc. for any of their albums.

This type of information is not available for ALL vinyl albums; it's only one example of what you can find with a little digging.

Good luck.
Michael Fremer within the last year in Steeophile answered this question, somewhat. I don't remember if his was label specific or in general but you should be able to check last years pretty quick at a library and find out what he had to say. Something about the last numbers on the inner groves by the label indicating when it was pressed. Do not quite remember it all. Hope someone else does to refresh my mind.
Record weight for reissues is 99% marketing hype rather than any indication of quality. True, vinyl in the 50's was much heavier than the flimsy stuff that got produced in the 70's and 80's but there is much more involved in determining the quality of an LP pressing than the thickness of the vinyl.
(I have plenty of flimsy 70's original issues that are every bit as good as some 200g reissues)

Experience, experience, experience! Plus read up websites (Google search on your favorite artists and labels), ask retailers and collectors, go to record fairs and hang out with the people there.

Any specific questions, and we'll be glad to help. But it does take years and years of getting to know the records... there's no substitute for experience. It's just like collecting anything.

thanks guys

wow - that Pink Floyd discography is extensive

I found a few tips on columbia and blue note references online and picked up the book Warman's American Records as well as a Goldmine to keep the shopowners honest. I'm more into the clean recording and dynamics of the music than collectibility. So less $$$ outlay and more flipping through bins and online.

Jazz looks pricey, classical should be inexpensive to get standard rep. more pricey with first pressings I'm sure

I used to collect japanese pressings in the early 80's of seventies material. thank God I taped them once to my Nakamichi and never again played them

I picked up a Loricraft and can't wait to find some more good inexpensive vinyl nearby that isn't too beat up. Estate sale anyone? Hear in New Orleans auctions are mostly antique furniture.

Already picked up a few Yes Red/Plum first releases and a few early 60's blue notes on ebay that I just happended to run into. Next maybe a road trip.... Princeton Record Exchange looks like a paycheck...
Get on Steve Hoffman's site. A lot of info on stampers there.
I have 2 pressings of one LP: one label is laminated and the other is not. Anyone know which one might have come first? The label color is also different but everything else is the same. Thanks!
Get the book " The Record Label Guide for Domestic LPs " by Joe Lindsay.This is the reference book on dating LPs by label art.
I found a site that shows some pages of the aforementioned book it is:
As I remember it, the number stamped between the end of the last song and the label can indicate is if it's a re-issue, if it has a - and then a number. BTW, there is some correlation between thickness and quality of recording, based on some original pressings(not speaking of audiophile re-issues here). For instance, "Elephant Mountain" by the Youngbloods has 3 different thicknesses. The thickest(earliest)sounds way better than the other 2 thinner ones. I've not seen this thickest one for sale anywhere.
Stereophile did have an article explaining the writing on the dead wax.I think it was M.Fremer.Very good explanation!Does anyone know what issue that was?
Thanks for all your answers.

The info stamped in the dead wax is the same on both LPs that's why I'm extra perplexed. But the thickness of records as mentioned by Mmakshak is interesting to me because one of the vinyls I'm talking about is thicker than the other, has a different feel and is heavier. It's almost like a 78rpm grammophone record!
Any more info you might have is more than welcome. Does anyone know if labels from any particular period were laminated?
Is it true then that thicker vinyl usually indicates an earlier pressing?
