Sonlarson, you describe yourself as a world silver collector, but you sure have some very nice Al coins!! Impressive. Do you separate your coins per their composition? Or are your Al coins kept mixed in with each country?
I do have an extensive collection of World Silver Coins, however I also collect a variety of other types of World coins. Including U.S. My World coins are collected by country and grouped accordingly. I also tend to collect by themes from time to time. My collection is very diverse. Sometimes it difficult to figure out what goes where. Since I am currently working on World Mint and Proof sets, I find a mix of everything, including the World Silver coins for my main interest.
Not if you include the numerous counterfeits. By the way, the Litzmannstadt/Łódź ghetto was not, or not built as, as a concentration camp. It was a (fairly poor) quarter of the city where the Jewish population was imprisoned under horrific circumstances. But as the inscription suggests, the ghetto had a council that would do certain administrative jobs. That included the distribution of such coins (so that the Jews could not use the money that the rest of the population used) but also the preparation of the "selections" ... Christian
Just because aluminum is a cheap metal doesn't mean that all coins are cheap even in circulated condition, especially some key dated coins. Take for instance these two. I'm somewhat suspecting that the Manchukuo coin may be a counterfeit since it is very scarce.
Aluminum coin story: I was in Japan in the mid-60's while the 1 yen coin still circulated. You could float it on water! It was light enough that the surface tension of the water was enough to support it. You had to put the coin out towards the end of a finger, then carefully and slowly immerse your hand (back first) into the water until the coin finally got there -- and it would float off.
In my catalogue neither coin shows mintages. But the Y# 12, is expensive. Because it is costly does that mean it is low mintage, I guess that is a safe assumption. I like the Y# 525 much better, I assume that there are more of them around. Nice information! Thanks. [PS: Just revisited some of your website, awesome!! Lots of mindboggling work!!].
