This First Day Cover (FDC) from the Straits Settlements, issued for the 1937 Coronation of King George VI, sent as a registered letter from Kuala Lumpur (KL), Federated Malay States (FMS), and addressed using a "Bowie envelope."
 * In ebay the standard Straits Settlements 1937 Coronation FDCs (even registered, but from more common post offices like Singapore or Penang, and possibly not Bowie envelopes) can range from: £19 - £50 (approximately $25 - $65 USD).
 * A "STRAITS SETTLEMENTS 1937 CORONATION FDC REGISTERED SINGAPORE BOWIE ENVELOPE" was listed for £19.00 on eBay UK, and another for $25.45 USD. This gives a baseline for a common Bowie FDC from a major city.
 * The "KL FMS" registration is a key differentiator. This makes it potentially more valuable than a similar FDC from Singapore or Penang. This FDC is likely to be on the higher end of the range for 1937 Straits Settlements Coronation FDCs, and potentially more.
