Does anyone remember what price OS Lion was when it came out?

I finally upgraded the memory on my old but good iMac (don't ask the year, I don't want to jinx myself) so my son could have a smoother experience on his new obsession, Minecraft.

I decided I might as well upgrade my OS now that I can, but my computer is still too old for Mountain Lion, so I figured I would look into the next best thing, Lion, which is still available on the likes of Amazon etc.
