Can someone please help me identify this Austrian coin [Resolvido]

This coin has all the characteristics of https://en.numista.com/catalogue/pieces744.html except it's aluminum and weighs 1 g

How do you know it's aluminium and what kind of scale are you using?

Because of the date it should be a proof zinc coin and those will not look like your run of the mill world war 2 zinc coin. If you are using some kind of kitchen scale it's tolarance alone might be a problem for such light coin.

Here are examples of Austria# 2875 in different conditions:



I guess your "aluminium"-coin is just a normal 1994-PP-zinc-coin (like Idolenz already said). Probably you had the idea with aluminium, because new zinc-coins look so shiny in contrast to corroded ones.

I agree with Idolenz that we need to know how accurate your weighing is. But if it is accurate, 1 g. for a 19 mm aluminium coin would make much sense.

If you don't have a good scale, I suggest you try to find coins of 1 g. and 2.5 g. in your collection by using the catalogue and compare them to your coin.

​I agree, zinc coins look like aluminium when they are new or close to new.

Thank you all. I finally found a proper scale. As usual you were right on the money.
