Thank you for your response.
To clarify, I did not intend to propose the inclusion of those Instagram-linked accounts as catalogue issuers in the strict numismatic sense. Rather, the links are provided as examples of privately minted silver rounds and bars produced in Indonesia by a number of active private mints or bullion fabricators.
Indonesia does have several domestic producers of silver bullion, and while they may not be "issuers" in the traditional sense (e.g., national mints or central banks), they mint and circulate collectible silver pieces which are often of interest to regional collectors and bullion enthusiasts.
The Instagram links were merely references to some of the silver coins and rounds already released by those respective producers. They were meant to assist in identifying visual designs, themes, or hallmarking styles—not to propose them as official catalog entries.
Hope that clarifies the intent of the post. I'm happy to provide further details or photographic references if needed.
