1967 Chile 10 and 5 centesimos

Here is another one, looking for an opinion of what this is.  It should be a bronze color, correct?  It looks like aluminum only.

See pictures on the scale with weight.  

Appreciate any comments on this.  

5 centesimos

10 centesimos

Definitely not aluminum with those weights.

For your messages, always link the possible coins in question, for example N#2949

And give size along with weight.

Ok ill link them in the future.

The weights are shown in the pictures. The weights are close to your link weight but not exact.  What do you think these are?
