I didn't think of this before I had a pot of coffee in me, but Krishna's usual photo chronology will probably help ease the buyer uncertainty factor a bit. In this case, people *will* be able to see what is under the paint.
Breaks on EBs do seem to affect the selling prices, but I don't recall it being as dramatic as 50-60% like Krishna mentioned. The neck-heel break EB-0 I bought from him is one example - that was probably more like a 30% hit. I don't think most buyers know that breaks can be just as good or stronger than original. And every once in a while you hear of that bad repair that fell apart and had to be redone.
It's hard to compare a rare sparkling burgundy EB-2D to a run-o-the-mill EB-0, though. That gap might be even less - especially if its on Ebay for a week, $1 starting bid, no reserve, great pics, the crowd goes wild, bidding frenzy ensues, and auction closes on a Sunday night. It'll be a gamble.
