I Think I Might Have Bought A First Edition

[Quasimodem]

The book is called Life In Double Time - Confessions of an American Drummer by Mike Lankford.

I checked the internet and there is a price on the inside of the dust jacket, and on the copyright page the numbers 10 to 1 appear with the 10 being on the left of the line.

I know that identifying a book as a first edition varies, so I 'm hoping someone here may know of another step that I might be missing.

I found the book for .50 at Big lots and here it is on amazon. As you can see, the prices in different versions are all over the place.

I know the book may not be worth anything at all, but I'm kinda excited since I've never owned a First Edition before.

Thanks
