bucktail, I'd say you done real good. $6 for that skillet is a steal, even if it's not pristine. You can fix that, pitting aside.
No pics, but I would suspect this one doesn't have the heat/smoke ring and is completely flat across the bottom.
To buy one elsewhere, such as fleabay, would run you at least $25, and up to around $75 tops. Although, some "collectors" ask much more, upwards to $150 or so. Saw a very nice #9 with heat ring sell for $201 recently on fleabay! It's just a matter of what the market will bear, and whether you have someone in a bidding war with you or not.
