Certified Elemental Metals/Materials Set! Can/Should I add anything?

Hello,

I posted a similar thread to this one sometime early last year but I made some changes/added some items to the set and I would like to ask the same question again. I been putting together a certified elemental metals/materials coin set for a while now that contains the different metals and the few materials used for circulating coins throughout history. So far I have an example for: aluminum, antimony, clay, copper, fiber, gold, iron, lead, nickel, palladium, platinum, silver, tin and zinc. From my research I think that this is all of the metals and the materials that were used in circulating non fiat coins. I left out the magnesium/aluminum alloy coins of WWII Poland and the manganese WWII US silver nickels since they weren’t the primary metal in the coin. I also, left out the all of the exotic metal modern commemorative coins since they were never designed for circulation. I would also like to leave out any modern fiat coins where the metal value was/is worth less than the face value at the time of production.

So, my question to you is does anyone here know of any other coins that I can/should add to this set? Below are the photos of the coins that I have so far in the set in order as said above. Please let me know what you think and please let me know you have any questions for me. Thanks.

Best Regards,

-Kyle

Steel.. Or is that the same as Iron?

 

Maybe the glass US cent?

 

The 1943 glass was experimental.
I thought of that one also.
I think the OP is stating actual official minted and circulated coins.

 

I can't read.

 

I really like this set. I'm curious about this restriction though:

Other than the word "modern", wouldn't that apply to every coin you've shown? So do you mainly intend on saying that you don't want "modern" coins in this set? Or have I missed your point?

 

Orichalcum From ancient Roman coins. Electrum too. You could probably find other metals if you ask in the ancients section, as there may be more I am unaware of.

 

Transnistria plastic coins:

 

Irradiated dime, perhaps? The process turns some of the silver into cadmium.

 

The point was the difference between commodity coins and fiat coins. I’ll try to explain it better. Yes, for the most part the set contains modern coins but the key word is fiat.

Let me explain it in terms of United States quarters. The last year the US made a silver quarter for circulation was in 1964. The US silver quarter of 1964 would be classified as a commodity coin since the silver value of the coin was worth a quarter when the coin was made. So even if you melted down the coin it had a quarter worth of metal in it in 1964 dollars. In 1965 the US switched to a clad quarter which would be classified as a fiat coin. Meaning that if you melted down a 1965 quarter the value of the metal was worth significantly less than a quarter in 1965 dollars. Both quarters are modern coins but one is a commodity coin and the other is a fiat coin. I hope this helps. Please let me know if you have any other questions for me.

 

I’m trying to stay away from alloys that the main metal in the alloy is already in the set. So it’s a little too close to iron for me. Thanks for the thought though.

 

I’m trying to stick to coins made by governments and not post production changes. Thanks for the thought though.

 

Thanks for the thought but to my knowledge all of the bi-metal coins that circulated contain the metals that are already represented in the set. Also, I don’t really want to include any fiat coins otherwise the set will get too big.

 

Palladium should not be included if you are restricting this to circulated coinage only. As far as I am aware, no country managed to have circulating palladium coins.

 

I originally thought that too but then I found out that the 3 coins in the palladium 1967 Tongan coronation set did circulate for at least 2 years or so in the country of Tonga. The set was 1/4, 1/2, and one Hau. One Hau was worth 100 paʻanga. The paʻanga was pegged to the Australian dollar in 1967 which was worth $1.12 USD at the time. So one Hau had a face value of 112 USD in 1967. I included a 1/4 Hau which had a face value of 28 USD at the time. Palladium was only worth about 50 USD an ounce at the time. The coins in that set just had a really high face value.
