Seen Before But Don't Remember- Now I Have One

It is not a mutilated portuguese coin. The designs, the shield, would be simpler than those.

Thank you so much for the reply.
Since my post, and with your reply, I came across Peru, Lima mint, 2 Reales, agree on 7-blundered2?-1
4 grams and specific gravity is 6.87- certainly not silver.
Not that it is- but what it may imitate.
Has what looks like a visible seam as a casting in a mold partly obscured by refected light.
Can you explain Potosi Pillars?
Is that just a design?
So a piece can have "Potosi Pillars" with a simple "L" as a mint mark?

I read with interest in the first pages of my catalog that the type is "Pillars & Waves".
So yes I misread "Potosi Pillars".
The waves bow up in the middle on Potosi coins and bow down in the middle on Lima coins.
One of those small details a novice such as I won't see at first but experts like members here with experience readily notice.

I have a better understanding of this piece now.
I knew it was a junk pendant trinket- but what?
After the replies and after the catalog, I took another shot correctly rotated.
I see the wave bow up in the center, a clear 2 on top and a P in the upper left corner for Potosi.
So a Potosi mint mark must mean Bolivia?
Or did the Potosi mint strike coins for other countries?
If so, those might be the monogram instead of the plain P?
Maybe I should search and read up on the Potosi mint.
One aspect about my hobby is that, even though some pieces are worthless junk, still one needs to understand what they are supposed to be. To that end even worthless junk has educational value.
