I am reminded of being in a coin store in the 1970's when a woman brought in her late husband's collection of highly historic and highly "collectible" silver rounds in the plush mahogany case. The dealer gave her spot, turned out the rounds into his junk silver bucket and offered her the case back. You have to find the correct place to flip something like this.
I suppose the dealer could have been a bit more rude if he put his mind to it, but it would have been a challenge.
My brother accumulated a complete set of Franklin Mint 1oz silver ingots of antique autos stored in a nice wood case. during the height of the last silver boom, we sold it for spot to a local dealer in Knoxville. The dealer didn't want the nice wood case. We gave it to him in return we got a smile.
I always consider the silver value and content of any coin that I buy for this reason and try to find a comfortable range. If I want the coin for the coin, then I must realize this can happen. Silver dealers want silver, not art.
Wow - I never knew there were so many variations. The one with what looks like the Star of David got me curious - third row from top and fourth from left (looking sideways). Did this come with a brochure or pamphlet showing the flags in color? If it did, I wonder if the colors were always some combination of red, white, and blue?
