I have a couple of dummy cakes from a recent cake show. Was just curious if anyone here has ever sold them and at what prices?

It is probably better to take off the icing and re-use the dummy. I don't think I would want someone having one of my cakes to do with as they please. With the dummy in hand, someone could easily claim it as their work.

Yes, i agree with that.

If you are doing fondant cakes, a friend of mine has a great little tip for doing dummies: she shrink-wraps the dummie!

You can decorate with fondant-or royal, if the shrink wrap has no wrinkles, then when you are done with it, the icing/fondant comes off slick as you please!
