El Salvador 5 colones 1997. Question [solved]

Good day to all

Please, help me to find any information of this coin (excluding information about diameter, weight, metal)

https://en.numista.com/catalogue/pieces75475.html

In Numista's catalog, they have got this information:

Not released for circulation.
Less than 25 coins known worldwide.
Update : 100 pcs were found in a bag. Several are sold already.

Can somebody give me more information about this coin?

I would start by messaging the El Salvador referee to ask for the source of where this bag was discovered.

Sorry, can you say me, who is El Salvador referee?

Erdvilla.
