Ethiopian coins

[bart]

This weekend I received some coins from friends who had visited Ethiopia. They look brandnew and I want to know if someone could tell me the year on these coins.
Also, these 3 coins are magnetic, so I presume there has been a change of metal from Copper-nickel to Nickel plated steel and from brass to brass plated steel. Can someone provide some information about a possible change of metal?
Thanks a lot,
Bart

Have a look at this link, Bart:

It doesn't mention metal, but the RCM made the coins, so maybe they changed the metal too.

This clarifies a lot! Thanks!

? Additional types were minted in EE1998 and EE2000 as per the link.

The shown pieces are dated EE 2000. Pieces with this year are still used this year getting new coins from the bank.

I just checked magnetism on the other Ethiopian coins in my collection: the 1969-issues are non-magnetic, as could be expected for a copper-zinc alloy. on the other hand: the EE1996 and 1998 issues from the British Royal Mint are magnetic, so I believe there has been a change of material there which is not in Krause. As I mentioned earlier, the EE 2000 issues from the Canadian Royal Mint are also magnetic (steel blankets?).

coffeetime already pointed out the article in World Coin News, telling that the Canadian Royal Mint issues were slightly different of the British Royal Mint issues. Still this variety didn't find its way to the Krause world catalog.
