Quartz epimorph after Baryte

I have just collected some specimens of quartz epimorphs after Baryte from North Herodsfoot mine in Cornwall. I can only find a handful of references on the internet to this coming from this location and these are all old time specimens.
All the specimens are 70ish mm X 70ish mm and all of the same quality as the one in the photos. I am struggling to find a value for these specimens for catalog purposes. Is there any one out there with any idea as to thier value.

Well, now that North Herodsfoot is open again for (at least some) collectors, all bets are off as to the value of these things, as clearly they're coming out again, so even historical prices of these specimens won't have much bearing - sorry!

Probably not more than $50. Don't quit your day job yet.

Thanks for that, the day jobs just fine at the moment. But we can all live in hope that one day we just might!!!!!.

If they were nice complete epimorphs, that actually looked like something, they'd be cool. But as is, they look like colorless drusy quartz... so maybe five bucks to the average collector.
