A UK 1st pressing usually has 3 cut corners on the insert (sometimes 4 corners), but so do the represses from 1975 (their were 2 represses in 1975 also, which are generally less valuable). From the photos it's tough to tell what condition the vinyl is in (excellent, very good, good, etc) but if it's truly a UK 1st pressing in excellent condition it could be worth a couple hundred US dollars, more or less. Also the run out groove info (found in the deadwax nearest the record's label) is tough to tell from the pics. Discogs.com will help you with more info and pricing. Cheers.
