I saw one of my grail guns several years back at the Louisville Gun Show. A guy had a table with only one gun on it, and it wasn't even put together! That's cause it was laying in its oak and leather case.
It was a Royal Grade H&H double in .577 NE, hand detachable side locks, 3 Leaf Rear, Gold bead front (as in GOLD) with a huge flip up ivory night bead, fully engraved, gold inlaid elephants, brand new, all accoutrements like the ivory handled turnscrews, oil bottle, cleaning rod, etc, etc were present. I actually thought it was priced reasonably at $100,000.
He wouldn't take my check.
(I didn't really offer to buy it- couldn't)
