ly surface publicly, and a guitar’ s history can be long, partial, and selectively remembered by the time it reaches a serious buyer. Knowing who owned an instrument, what work was done, and when is worth real money, because in this market, the story is part of what you’ re buying, and an unverifiable story is worth considerably less than a documented one.

Eighty years of ownership leaves a record. Some of what gets done to these guitars is honest maintenance— a neck reset, a refret, a reglued brace. Some of them are covering tracks. The buyer who can’ t tell the difference pays for the uncertainty.

An overspray on a D-45 moves value from the mid- $ 400,000 range to $ 150,000 to $ 200,000. A replaced top on a D-28 costs tens of thousands in value regardless of how clean the work looks. The further from original, the further from value— and the gap between a pristine survivor and a well-disguised one isn’ t always visible until someone who knows what to look for gets the guitar in hand.

As intact examples thin out through loss, undisclosed alteration, and repair work that seemed reasonable at the time, the ones that remain uncompromised become correspondingly harder to find and correspondingly more expensive when they surface.

The real market runs through dealer relationships and collector networks, which means the published ranges consistently describe where prices were, not necessarily where they are. Months can pass at the top tier without a visible transaction. The collector community around these instruments is small, knowledgeable, and tight. They find each other without auctions.

Martin’ s Project 91 series— ninety-one new D-45s, each built to the specification of a specific original by serial number, priced at $ 150,000— makes most sense when read against these kinds of numbers. With prime originals trading between $ 350,000 and $ 520,000, the gap between a documented new build and a vintage survivor of uncertain history has narrowed considerably. For the full story on Project 91— its construction, its Brazilian rosewood sourcing, and the reasoning behind its price— see the companion feature in this issue.

The population of pre-war D-45s will remain ninety-one. A third of them are already compromised. The supply of unaltered D-28s shrinks a little every decade. The buyers capable of spending six figures on an acoustic guitar have grown in number for as long as anyone has been tracking this market. Those four facts have been true for 30 years and will remain true. Everything else in the valuation picture follows from them.
