Thrift find - box of 8 first edition Harry Potter!

This box of books came off a truck of my friend's thrift store last week. When I saw it was Harry Potter I wasn't too excited because I see them all the time.
But when I saw they were printed in the UK, I bought the box.
At home I found out they were all 1st editions! (but different printings)
There were 8 books, but 2 were a copy of the same.
Any info on these, the printing # & anything else I should know would be greatly appreciated!





This has a typo Anglesea that the spelling was changed in later printings.
Does the number line mean it is a 12th printing of a 1st edition?
Thank you!

"The print line on the copyright page must read “10 9 8 7 6 5 4 3 2 1”, ten down to one, exactly. The lowest figure in the print line indicates the printing. (For instance, if your copy has “20 19 18 17”, it’s a less valuable seventeenth printing.)"

 

Yes I saw that - I know mine's not a firt printing even though a 1st edition - but mine goes numeralicaly up & then down and skips some numbers & ends up at 12 instead of in chronological order - is that still the 12th printing?

 

I think so, based on:

"The line sequence could ascend or descend or even have no discernable order depending on the publisher. All of these sequences below are first editions.
1 2 3 4 5 6 7 8 9 10
10 9 8 7 6 5 4 3 2 1
1 3 5 7 9 10 8 6 4 2
(All first editions)

Sometimes the number line is also accompanied by the words ‘first edition’, but be careful because some publishers leave on the words ‘first edition’ even when the book is in its third printing and that fact is reflected in the three in this number line.

First edition
3 4 5 6 7 8 9 10
(Third printing)"
