I suspect the demand wasn't there - they were asking $20 for a copy of a record that can easily be found for $10-15.

In this pic, you can see the catalog # is SS2 201, and the tiny number on the bottom starts with ST and ends in PR. I assume ST stands for Stereo. The PR tells you the specific pressing plant (Presswell) that manufactured the record. Some companies don't specify that on the label but do in the run-out etching in the vinyl between the playing surface and the label itself, usually with little symbols. The CRC on the left side refers to Columbia Record Club, which is a mail-order only club here in the USA.

These links are helpful but don't really answer the question. The numbers and letters on the label will refer to the catalog number (in this pic you can see it's 124). The small numbers (45-ATE-111) offer more detail - I figure the '45' is obvious. Who knows what 'ATE' means, but the 111 is specific to this side. The other side has 45-ATE-110. Usually you can assume 110 refers to the A-side and 111 to the B but that's not always the case.

My biggest mistake as a new collector was overpaying for records in poor condition. Check out popsike.com and gripsweat.com to determine the prices of the records you want, and pay attention to the condition. And see if there are issues in the seller's feedback - many will look at their inventory with a 20-watt bulb from 10 feet away and declare that it's 'Near Mint'. Also pretty much any Zeppelin record that sells for $200 or less will turn up for sale online once every 2-3 weeks, so there's no reason to get into a bidding war because another will come along soon enough.

Odd to see it in a III cover.... these turn up from time to time and are slightly more valuable than a regular pressing.

I just picked up Makundju, which means I now kinda sorta have the Final Option, at least all the parts...

In the $30-50 range

Anything you buy on this site is going to be a recently-produced reproduction. If you want an original, you'll have to sift through all the fakes on ebay.

I wish it had this cover:

Suggestion for next episode: the promo blimps.

Cool episode... though you missed the holiest grail; at least one stock copy of the Japanese 'Immigrant Song' exists.

The rarest mistakes are when one side of the record is from an entirely different release. This 90's release of Houses has a Green Day record on one side and supposedly sold for over $1000: htps://www.discogs.com/Green-Day-Led-Zeppelin-Dookie-Houses-Of-The-Holy/release/7184799 The price seems way out of line but all it takes is one looney.

I think the most prized misprint is the few pressings of the Irish edition of the 4th LP that had Asylum labels: https://www.discogs.com/Led-Zeppelin-Untitled/release/6420213 There was also the Turkish sleeve for the Immigrant Song with a misspelled title: https://www.discogs.com/Led-Zeppelin-Immigrant-Song-Hey-Hey-What-Can-I-Do/release/4520637 Allegedly when they realized the mistake they just pulled the sleeve and didn't release a corrected version.

For an official Atlantic issue, that is probably the record. There are some Taiwanese and Korean pirates that completely butcher the English language.
