I don't see what about the original posts would have made someone rush out to start setting up a market for these. Obviously that collection is priceless. No owner of a collection like that would be looking for prices on a web forum.
Priceless is the size of it.
I am a member of the SCA. Society for Creative Anachronism. We are the wack jobs that dress up in armor go out into a field somewhere and beat the crap out of each other with PVC pipes wrapped in tinfoil. It's a lot like paint ball but up close and personal. The site of the worlds largest medieval battle reenactment ( Pennsic ) is about 10 minutes from my house.
I'm not an arms expert but I do know that each one of those suits of human armor would sell for between $10,000 and $20,000. If we say $10,000 and multiply that by 40,000 full suits then just the human suits of armor are worth $400,000,000.00 I have no idea what a full horse armor would be worth.
The rest of this is just general information and not specific to the pics or this collection.
The suits weigh between 75 and 100 pounds and there are many myths about them. The most prevalent one being that a knight once knocked onto his back was helpless to roll over and get back into the battle. Nothing could be farther from the truth.
Wearing 100+ pounds of steel and carrying another 50 to 75 pounds of weapons and shield these warriors were agile, mobile, and hostile. Regular training regime included running 5 miles in full armor. Running a confidence course including scaling a tall wall, rope climbing, monkey bars, and balance logs. Also in full armor. In general a Knight in armor was expected to be able to nip up from a prone position and mount a horse with out use of stirrup or saddle. Their strength and stamina were unreal. No one in the NFL is in better shape than these guys were. Many wore the armor all the time even sleeping in it. Only taking it off for the bath or... Well you figure out why else they might want it off. That is what the Ladies in Waiting were waiting for. For Sir Knight to get undone.
Awesome collection.
The armor of the higher Nobility would often be engraved or embossed and inlaid with gold.
These guys were bada55.
