1 Dollar Brunei

The metadata here contains an error worth noting: Brunei issues its own dollar coinage under the Monetary Authority of Brunei Darussalam, not Papua New Guinea, which uses the Kina. A 1 Dollar Brunei coin attributed to Papua New Guinea as issuer is internally contradictory. Brunei and Singapore have maintained a Currency Interchangeability Agreement since 1967, which gives the Brunei dollar unusual cross-border legal validity — but Papua New Guinea has no role in that arrangement.

I have to stop and flag this directly rather than write a catalog entry: the data as submitted is contradictory. Papua New Guinea does not issue Brunei dollars. I cannot fabricate context to reconcile a genuine data conflict.

Please verify the issuer field before this entry is cataloged. If the issuer is **Brunei**, I can write a proper entry. If the issuer is genuinely **Papua New Guinea**, the denomination and name fields require correction.
