I am not looking for an ID so much as a little more info...Here's what I know: The coin is iron. Made in Duren, Germany in 1918. Here's what I don't know. Is this considered Notgeld? Does it have much value? And most importantly, how do I stop the rust? Here it is: Image:  1918StadtDurenO-web.jpg71.26 KB Image: 1918StadtDurenR-web.jpg63.79 KB Even though it's in horrible shape, it's one of my favorites. I really like the design. And best of all, I got it out of the 5/$1.00 bin at the coin shop! |

Unfortunately it's an irreversible process and it's clearly damaged as you can see the pitting. Still interesting though.

Yes it's a notgeld coin, in the condition that it's in it really doesn't have much value. Even in UNC condition they are only worth a few dollars. There isn't much you can do about the damage, a coating of RENWAX will stop it from rusting further but not reverse what's already there.

echizento,
Thanks for the recommendation. I knew I couldn't reverse it, just wanted to stop it. The Renwax makes sense. Keep oxygen away, and it won't rust anymore...
I also have some zinc coins that are corroding. Is the Renwax a good choice to stop zinc corrosion?
Can the zinc corrosion be removed? Should it be?
Thanks for the help!

German notgeld coins come in a bewidering array of types and verieties. I have a zinc 10 pfennig from Duren dated 1917, and it looks nothing like yours.
As for corrosion on zinc and iron coins, these "coins" were made in a wartime and post-war emergency; the last thing they had on their minds was what they would look like in a hundred years time. The metals they chose are highly reactive to air and water. There's not much that can be done once it's there; any chemical treatment we might try to remove the corrosion with is likely to cause even more damage. The best we can do is seal it up (Renwax, an airtite or even a 2x2 is better than nothing) so it can't get worse.

I've got two or three of the old Iron Stadt Duren notgeld coins - If I remember right, its actually Steel and not pure Iron (pure Iron will begin to noticably oxidise really fast). They're interesting coins and kind of mate two of my pet interests; German Coins and Iron-based coins.
During and just after BOTH world wars there were quite a few Fe-based coins. WW1, Germany minted occupation issues in Fe (1,2 and 3 Kopeken; 1, 5, 10, 20 Fenigow), several Notgeld designs (Such as your Stadt Duren 10Pf, the Stadt Gent issues and lots of places) and also minted 5Pf and 10Pf for regular circulation in Fe...
Come WW2 and Iron is Back! Occupation issues from Poland (50Gr) and some Scandanavian countries (Sweden, Norway) to name just those off the top of my head!

SAP,
I have seen a picture of that 1917 Duren. Pretty neat. I have noticed (as you said) that there is a LOT of Notgeld. Just to preserve my sanity, I'm not going to start collecting Notgeld. Unless I find more in the "cheap bin"! And, thanks for the preservation info!
Zaggy,
I was hoping you would put in your 2 Pfennigs worth! I have seen on other threads that you are a German collector.
I have some questions on Renwax, but I will start a new thread with those.
Thanks for the info, everyone!

1. It's iron - not typical metal
2. It's from Stadt Duren
Yep...sounds like it was made for emergency purposes to me. Pity that iron rusts...

Well Schmidty, I'm always happy to talk German stuff - its interesting and you'd be surprised how much you can learn about a subject when i) you discuss idea's with others who have variantions or different ideas and ii) challenge your knowledge - helps you figure out what you don't know...
Like one of my research projects at the moment, is doing a detailed re-examination of known production numbers. This has resulted in a number of 'revised' numbers, errors and differences being found (when compared to the generally accepted numbers)... And finding these differences inspires you to dig deeper and try to work out how the original numbers were created and what alternate sources are out there...
Research is just fun! ;)
