Anyone else collects coins by different types of metal? I'm trying to assemble coins struck in different elements - missing titanium, manganese, zinc (should be easy - not looking at US penny because it's copper plated), niobium, lead. About to finish compiling a website that illustrates different kinds of metals in my collection. It does look quite neat. Some unusual ones:
There is a man called Jim and he is one of the most amazing collector that I've come across. He had all coins in various elements including a Russian 3 ruble platinum coin that circulated (struck in 1830s). There's just one that he needed - that is the antimony coin that a few people that I know have been chasing after. It's the first coin shown. He had a website but it seems to be down for a period of time. While precious metals are expensive because of the metal prices, I took years to hunt down the antimony coin. Try looking for one if you are up for a challenge.
It is a very cool idea for a challenging collection ! Congratulations ! I have found one announcement on ebay for a japanese antimony coin ( may be should we investigate it in details ) http://www.ebay.com/itm/1-pcs-1944s...2724016?pt=US_World_Coins&hash=item43b06cb8b0 Of course, it is not the same than yours
Froggy, I can guarantee you it's not antimony. It's a Japanese coin struck in tin 93%, zinc 7%. As far as I am aware, the only antimony coin as well as that did circulate is the Chinese antimony coin casted in Kweichow Province. http://www.charm.ru/library/antimony.htm There were times during the early history of China when copper was scarce for the cash coins, instead they were subtituted with higher ratio of lead and antimony especially in Kweichow province.
Many thanks gxseries ! I was a bit suspicious too, the link is very interesting and read it meanwhile ( instead of checking my Krause )
There's a zinc reichspfennig (or 5 or 10 reichspfennig, I forget), but I'm not sure if it's 100% zinc. But if it is, you could use that for your zinc coin.
Sounds like a great theme for a collection! 1942-1945 Jefferson "war" nickels are made out of 8% manganese.
Yes, it is - in fact, all three denominations: 1, 5 and 10 Reichspfennig between 1940 and 1948. Another option is the Austrian 5 Groschen coin 1948-1992; maybe it is easier to find a non-corroded piece among these. Christian
Yeah, Frank Robinson used this coin in his book as an example why you should just call if you get a list and it has something good on it. He said he picked up one of these for about $20 once, by a quick phone call.
Sounds like a great theme. The Austrian 25 Euro coins have been doing some exotic materials lately. As far as zinc, you may want to look to the German occupation coins from WW2. The Belgian zinc pieces are particularly easy to get ahold of. Are you also collecting the variety of alloys? For example, Aluminum Bronze is readily available in 5 or 6 alloys (or more).
I'm not going to collect by variety of alloys George as there's a never ending list of various combinations on a coin. It becomes more complicated with bi-metal coins. For example this: Core : Cu 65% Zn 35% Inner Ring : Cu 75% Ni 25% Outer Ring : Cu 75% Ni 4% Zn 21% Weight: 10.12g. Just writing up some comments under each elements on the site - looks quite good at the moment. Zinc coins should be easy and cheap - I just have to find examples that aren't too damaged. Thanks everyone.
A zinc coin (100%) that you could add to your collection could be this: http://romaniancoins.org/20lei1942.html 20 lei 1942,1943 or 1944 Romania. The mintage figures are pretty high and the coin should be easy to source. It also has the largest diameter (in the series there were also 2 and 5 lei pieces).
