Collector's Notes

1950s D-18s are excellent player instruments. The mahogany tone is ideal for flatpicking. Many were used professionally for decades — check for replacement bridges, saddles, and neck resets.

How to Authenticate a 1950 C.F. Martin & Co. D-18

Martin serial numbers are the most reliable in the industry — verify the number stamped on the neck block (visible through the soundhole) against Martin's published tables. For 1950, the number should fall within the documented range. Mahogany back and sides with spruce top. Non-scalloped X-bracing pattern for this era — verify through the soundhole. Mahogany (not rosewood) back and sides — verify correct wood species. Simpler appointments than D-28 (no herringbone). Check for neck resets, top cracks (especially near soundhole and bridge), and bridge plate condition. Tuners should be Grover Sta-Tite. Finish should be nitrocellulose lacquer with age-appropriate wear. Original case adds value.
