Pretty harsh . . . If someone thought they were going to profit by trading these "coins," I'd say "too bad." But if they were purchased because they were inexpensive and the buyer thought they were interesting, then I'd say, "so what." I see many coins purchased where the buyer just wanted it and wasn't looking for an investment. "..overhyped and overpriced.." could easily describe most of the coins coming out of the U.S. and Canadian mints.
My post that you quoted was really in response to the OP's question "Cook Islands? Why cook islands? Elizabeth?" I was also mistaken about the origin of the issue. I thought it was a private issue like all of those rip-offs that popped up on TV after 9/11. https://www.consumeraffairs.com/news04/2005/coin_scams.html
Well, if you purchase one of the supposed 1/10th oz Cook Island gold coins thinking it's one tenth an ounce of gold, you just got schnookered. Here's an eBay listing I just found (one of many). It's 0.24 percent gold, but listed in the one tenth gold content section: https://www.ebay.com/itm/2020-First...325700?hash=item217aa18204:g:lPwAAOSw~rBfdGgz
That is a great article. Times have changed it seems, along with public hangings and honesty. Which appear to have faded away at parallel rates.
Like other private mints, National Collector's Mint is out to make money, so offer the public jewels and bauble's in hopes of a profit. Silver stackers like some of their designs and will buy them.
"Collectables" seem tacky to me, they have a special place and we all love them. I have some myself...
