Not $1,000,000 for any one insulator. But he has put more than this out collectively for them yes. He has most of the one-of-a-kinds known in the hobby as well. Some of are the shelves in the same room as (one of) his Gatling guns...the one believed to have been used By General A. Custer.
I think the record for an insulator purchase is 150K (unofficially). Antique bottles have gone for more!
The other millions he has dropped have been with insulator-hobby go-withs such as his own antique steam engine with tender, mail car and caboose. He said he was told an engine was not called a "train" unless it had these 4 components. So he had to have them all.
When the local city was tearing down an old metal RR bridge for scrap. He paid them $2,000,000.00 to tear it down and rebuild it across the river running through his property.
He is the coin collector who owns all but one (I believe - unless got the final one) of the Y2K Sacagawea & quarter mule coins.
I asked him. Yes, he has a set of of one each of the off-metal 1943 and 1944 LWCs also, along with 1 million (yes) 1923 steel cents. The huge jars I saw containing some of them looked to be MS as well. Being in arid New Mexico makes it easier to keep them in MS.
He has a DC9, F16 (wrecked ones were legal to buy and own - and he had it restored), a customized cadillac ordered by Elvis (but never delivered due to Elvis' death), an M1 tank, the insides area of a B17 where Boxcar Willie served in WWII, and his mansion is made of polished petrified rock found on his property.
All of these things he keeps in 3 of his museums (including the largest private collection of stuffed animals in the world - many of them obtained like the White Rhino that died in the NY zoo and he got it from them) which are always open to the public and schools by appointment. For which he pays a local as a guide to come in and give the tours (no charge to the people viewing the museums).
There really is MUCH more (like his stage coach, steam tractor collection, etc.)
He also got his pyrotechnic's license and makes his own professional fireworks. He puts on (designs, and sets off) a huge fireworks display for the city each year on the 4th...all out of his own pocket. Since he makes his own fireworks, they are more colorful (each individual firework) than any I have seen professionally on TV or otherwise. What I mean by this is he has all the colors of the rainbow in just one shot.
He once wanted an anchor form a sea going vessel b/c he thought it would be nice for kids to climb on while picnicking at his place during museum field trips.
And seriously, there is much more.
So paying the price of that MS68 cent would go unnoticed by him. And if you have two such people wanting something, well...
And, BTW, a lot of insulator collectors are also coin collectors. I think appreciation of the history and beauty of the collected objects might be the tie between the two. I know for me it is.
