That's really neat about the niobium coin, I'll have to get that along with the polymer/metal ones they issued last year. A bit behind on modern things because of some recent purchases. For example...   Yes, I got me one of those Polish sulfur medals. I might have a reliable way of getting more, if so I will make sure you can get one of them, CCC. I also got me a Poessneck black leather/gold gilt notgeld, 1923. These things are fairly common (and pricey) but this one is particularly nice. The gold leaf is commonly broken or damaged on these.   |

So here are some interesting things that I came across recently. Pakistan made some Cadmium containing silver commemoratives in the 1970's and apparently the US mint kept really good records of what actively circulating world coins were exactly made of as part of the "Annual Report of the Director of the Mint" and I came across the 1951/1952 copy of that report on google and it seems that all of the Occupation Zinc coins from Norway during WWII had a .2% Cadmium content. As seen in the links below. http://www.chiefacoins.com/Database...Chaudhry.htmhttps://books.google.com/books?id=O...m%22&f=falseEdited by casualcoincollector

Those director's mint reports look like they're really useful. I arbitrarily chose another one -- the one from 1959 -- and in it I see that Italian coins made of "bronzital" include 0.4% titanium in the alloy.
I normally don't bother with anything less than 1% but there are probably some other hidden gems in there.

Thanks for the information on the Italian 20 Lire I hadn't come across that one yet. I hear your point on not including things that have less than one percent in the alloy but from my point of view if I plan on including plated pieces such as the chrome plated WWII Canadian Nickel, which definitely has less than one percent chrome I should also need to include the minor alloys provided that they have a metal that isn't represented somewhere else in the set and provided that it is not an impurity in the alloy. So, I will be adding a Norway occupation 50 Ore and a late 1950's Italian 20 Lire to my set. The titanium in the 20 Lire is definitely there by design and I believe that the cadmium in the Ore coins is also there by design since there are other zinc coins from that time period that do not list cadmium in the same report and cadmium is added to zinc to increase its corrosion resistance.

There's a lot there to be had. The 1959 report mentions that a number of South Africa coins had 2 or 5% manganese in them. Surprised me quite a bit as I thought our nickels were the only ones.

This thread was one of my favorites last time I frequented CCF. What do they call it when you mostly read but don't participate? It's not a stalker...lol. It's called a...crap I don't remember the word. If someone could help, my aging brain would appreciate it. Just got caught up from where I'd left off. Fascinating some of the materials that were creatively used for a myriad of reasons. Thanks for keeping the thread alive.
Is the word lurking?

@chafemasterj, Lurking is usually the term that comes to mind for me but I think that several terms would probably work. Here is something that I picked up a while back. Since I have been unable to get ahold of a Pismo Beach or Crescent City Clam Shell Money that was produced in 1933 during the American Great Depression regardless of how hard I try. I have settled for a modern variant for the time being. It was only produced a couple of years ago but it is a monetized shell that is still redeemable today. So it will suffice for now.

Thanks for the nudge. I've been getting tons of new things, just not really new materials. Here are a few, and I'll have to put more up too.   Despite the post office's best efforts, I finally got me my own lava meda.   This is the first, and thus far, only playing card notgeld of this type I have. (Speaking of which, someone I know 'owes' me a much more interesting one...)   This is one of the earlier Canadian municipal trade tokens. While I imagine most leather scrip is made of cowhide, this is one of the few that explicitly mentions that.   This one is not mine, but I finally got one of my own last month. The commemorative myrtlewood 50c token with the golden sticker is fairly rare. (The plainer one without a sticker is pretty common.) |
