I'm changing this I thought it was a soft cover...duh. OK it looks like your right at least $10 even tho some $5 ones didn't sell. There are ones on ABE Books listed for stupid high prices & eBay ones are all over the place but I'm not reading the ads to see what printing # they are if it's not in the title. Oh and I'm not sure if that 2 thru 10 means 1st printing, 2nd printing or 10th printing from how its written. Some books are misleading trying to decipher that code.
You're reading it correctly, it's a second printing of the book. In that condition (with markings and creasings on the cover), I would guess that your closer to the 10 vs the 30 although, with the right buyer, anything is possible.
