Call me an amateur armchair architect if you like, but this characteristically stark looking edifice looks like it could well have been designed by Frank Lloyd Wrong.


I thought he was a big fan of steel structures. Or was I wrong?

Kaiser Wilhelm

You’re partly correct, Craig. Frank Lloyd Wright did use a lot of steel in his structures, but that material was employed primarily for support rather than as design. The principal and therefore most visually apparent and artistically striking element of his architectural masterpieces was in fact massive amounts of concrete.

Kaiser Wilhelm

As another example of one of his concrete structures, there’s the Guggenheim Museum in New York City, an exceedingly prominent instance of the use of sprayed rather than of poured concrete.


It’s a good think he made use of reinforced concrete, otherwise the cost to maintain these unique structures would be prohibitive indeed. I always appreciated how he incorporated and was inspired by elements of nature, as seen in your first insert. That’s a house I’d look good in! Lol

Kaiser Wilhelm


You have stumbled upon a unique irony in this particular case. Apparently while he was so intent on making the house stick out so far from the waterfall he rather seriously under-estimated the amount of steel reinforcement required to hold up the weight of all that protruding concrete. Subsequent testing in later years showed the entire structure to be on the verge of total collapse, and only due to the timely installation of additional steel beams was the house saved from exactly that sad fate.

Note to Mr. Mike Unser:

Mike, whenever I attempt to edit any of my comments I immediately get stopped in my tracks by a “Your Are Posting Too Fast – Slow Down!” warning that absolutely prevents me from changing any of my text. This has never happened before; is this a glitch in the system?

Seth Riesling

Mike Unser,

I noticed that same thing that Kaiser has come across when I try to edit a post & I’ve never seen that before – a big red box area at the top that states what Kaiser said.


Kaiser Wilhelm


It is as though there were an algorithm in place to prevent any editing from taking place. If that is indeed the case I for one can’t grasp the rationale for it.

Seth Riesling


Another computer mystery. I hope it’s not AI taking over this forum! Lol.


Kaiser Wilhelm


Wait. This isn’t how the Terminator got his start, is it, as a coin site bot?

Major D

Kaiser, Slow Down! You forgot to say the magic word: “mistake”. The only times I’ve seen Mr. Unser respond to a text is when you point out that there is a mistake in the article.

Major D,

That is all true, but calling it a “mistake” tends to signify that it is a personal error while terming it a “glitch” conveys the idea of an electronic malfunction.


>> “The new headquarters in Irvine will offer enhanced convenience for visitors, boasting several hotels and restaurants within walking distance”

I coudda sworn that nobody walks in LA (much less the burbs of LA)

Seth Riesling


Yep, walking in LA and the area will get you robbed fast, especially after visiting this rare coin company’s new modern headquarters building that thieves already have on their radar!
Take a bodyguard with you if you visit this place since they have some major, top-grade coin rarities inside!


Kaiser Wilhelm

Seth and c_q,

I see now I wasn’t alone in wondering about that observation in the company’s publicity blurb. “L.A.” vis a vis “Within walking distance”. This does not compute.
