Need help identifying error coin

Hi! Would anyone know what is there error on this coin? Thanks a lot!

Are you referring to the ridge of metal between the lettering and the rim?

My guess is that this might occur due to some combination of the coin's design, and the settings used on the coin press (inadequate pressure?).

I'm not sure it would be considered an error by most collectors, but it is an interesting effect.

Can't see anything wrong with your coin. Please take a look here:

Exactly, I was comparing it with this picture.

I used to have other Colombia coins with flow marks, indicating some inadequacy in the design or striking.  Here is an example:  

In this case, you can see flow marks radiating from the bust, along with weak stirike at the rim, which might signify the stamping force was not high enough.

This is why I'm not sure I would say it would be regnized as an “error”.

Those “rays” are rather common on coins from many different countries. Personally, I don't consider them as varieties.

look like a collar issue. But most likely warn out die.  Like this US dime

I agree. 

I've read somewhere that at the beginning of manufacture of a new coin type there can be some adjustment of the machine settings (process optimizaiton).

For my coin, 1967 was first year of issue, so maybe that example was struck early in the run, before the machine settings were optimal?

Lauruca, is you coin struck with coin alignment or medal alignment? (I just noticed that both are listed).  I would imagine that also affects how the coin comes out.

It is struck with coin alignment.
