Cracked Wagner

Okay, recently I won a bid on shopgoodwill.com and got three skillets, two Wagners and a vintage no-name. The square Wagner is a bit rough, but still good for bacon. I'll try some cornbread in it soon. The no-name has just a trace of rough near the center that pulled a bit off the crust of the first frittata I cooked in it, but the second came out nicely. (We like to plate the frittata rather than scoop it out of the pan.) The second Wagner is an older one, straight sides and the ring right at the edge. I also cooked a frittata in that one, and it came out perfectly. However, when I was washing it, I noticed a line of oil on the bottom of the pan (outside bottom). Closer inspection showed a hairline crack fully across the bottom.
Anyway, is there any reason I should NOT use the pan for pancakes and frittatas and similar stuff? I didn't have eggs running through the crack, just a bit of olive oil. And other than that, it cooked beautifully.
Just to be clear, I don't feel cheated. I felt like I got three skillets for the price of one on that auction, and if I can still cook in it, well that's fine!
Thanks for your help on this.
