How to determine if key is used

[SolarCanoe]

Hi there,
I have a store bought copy of iWork '08 and I have since bought office for mac. I no longer use iWork and i want to sell it on eBay, but when i was looking over the documents that came with it I noticed it had a product key included. Now I didn't think I ever put a product key in when I initially installed it so I tried installing it on my newer macbook (not the same macbook as it was originally installed on) and it never prompted me for a product key.

I want to sell this copy and i'm pretty sure the key has never been used, but how do I find out if it has? Is it fine to sell to someone? If it doesn't prompt me for a key, does it mean it wont prompt them?

iWork '08 prompts for the serial key the first time Pages/Keynote/Numbers is launched, or if running the test drive version, after 30 days. iWork '09 does not have a serial key if purchased in-store, only when an electronic activation is purchased from the Apple Online store from the trial.

I see this now. Mine is a store bought copy, I never bothered to open the program once I reinstalled it, and now that I have it prompted me for a key. So I must have input the key when I originally installed it.
Does this mean I can't sell it now, or will the key work over and over again?
Thanks

I don't think there's anything that excludes transfer of a license to another party. You own the key to the software and you're selling it - So long as you delete your install I think you're (legally) in the clear.

If your question was more to the nature of when the purchaser enters the key will they get an "already been installed" message, I don't think that will be the case. Apple is not (yet?) like Microsoft with blocking keys, only X number of activations, etc... I'm about 95% sure it will install on a different machine without problems. I'm thinking there's a 4% chance they will get a notice, but it will install fine, and about 1% chance that I am a jelly filled doughnut.
