I don't think any PROVEN have ever been offered publicly before. I think Ralph got his from Amir in a "private deal".

I am pairing a captive hatched girl with a Killer Bee this season. If she does not prove to be a Shatter/Marble I will be SHOCKED. Her markings are extreme. I have to get GOOD eggs from her -- first things first.

As far as price for a proven line?? What other Shatter combos look like will dictate what they sell for. I would guess in the $4000--$6000??? Whoever offers them first will control the initial release price.
