I think this is an interesting scan.  Care to pick the proofs?

Yes, the others are proof-like. Isn't it disgraceful that Austria was using zinc coins in peace time? By which I mean new design coins that were also developed and issued outside of war time - not the war time coins that persisted after the war for a few years. I think Albania was the only other country to do this.

Not that I like zinc coins, but ... heck, I don't know when the Austrians practically stopped using them. Must have been quite a while ago. :)  In the past couple of years before the euro introduction, the 10 Groschen coin (aluminum) was pretty much the lowest denomination in circulation.

I am not sure when they quit using them in circulation but the last Austrian one minted for circulation was 1992.
Did any countries have zinc circulation coins after 1992...not counting copper plated zinc?

Not too many metals used for coins could be a worse choice than Zinc. I can't think of any, even steel seems to last better.

I can only find four countries that issued Zinc coins after the 1940's;

Austria (last issue 1992)
Denmark (last issue 1972)
Albania (last issue 1957)
and Peru (last issue 1965)

The first image wasn't meant to be a trick, the proofs are the middle three.
One Nickel, one Aluminum and one Zinc.

Here is another Austrian Zinc proof this time from 1981.

What evil or depraved life led to this sorry state? Nothing, it did nothing worse than any of its brother proofs in the same neighborhood. And unlike the piggy who lived in a house of straw and perished for his foolishness, this littly piggy lived in an apparently substantial house of PVC for 31 years. It needed no big bad wolf to be the instrument of its destruction. Its own environment and a little time quitely and largely unnoticed did it in.

What makes this scan interesting is the contrast.
The aforementioned 31 year old proof and a 1804 year old (+/- 9) (actually dates circa 206 AD) circulation strike.
Isin't that amazing?

How can you all forget these 1,5 and 10 Reichspfennig German coins:

But those were only minted during WW2 and by the Allied post-war administration. So I would consider them to be "war related". In terms of "regular" coins, there aren't many ...

Absolutely. But then ... don't we know what zinc coins look like after a couple of years? So comparing the two is almost unfair. ;)

And yes, coins should by and large not be cleaned. But a while ago somebody treated an Austrian 1 Groschen coin (knowing that this is a common piece which can easily be replaced), put it in warm lemon juice for 30-60 min, and then rubbed it gently with sodium bicarbonate. http://img69.exs.cx/img69/2906/pict00049gi.jpg (not my image)

Ooops! That's scary. I can't see any telltale signs of cleaning. A time span of 30 to 60 minutes is a bit large and much will depend on timing. Too short and there'll be ugly spots left, too long and there'll be wear. He got the timing just right. Neutralizing the acid with sodium bi-carbonate is nice, but soap would have worked just as well, I think.
