Vintage Martin 0-18, 00-18 & 000-18 Value Guide
Vintage Martin 0-18, 00-18 & 000-18 Value Guide
Martin’s mahogany small-body flat-tops, the parlor-size 0-18, the grand concert 00-18, and the auditorium 000-18, are among the most musical and collectible pre-war American acoustics. Clean pre-war examples bring strong four to five figures. Edgewater recently paid $11,000 for a 1937 00-18 and over $10,000 for a 1940. Body size, era, originality, and condition set where any single guitar lands.

What Is a Vintage Martin Small-Body Worth? (Year by Year, 2026)
The values below are reference points for clean, all-original examples. They reflect what a fair buyer like Edgewater pays, not best-case auction results. Pre-war scalloped-braced examples sit at the top, and the larger 00 and 000 bodies generally bring more than the parlor-size 0.
Year and model | What defines it | Reference value for a clean example |
|---|---|---|
1935 0-18 | Pre-war parlor, mahogany, intimate body | Around $7,500 |
1936 0-18 | Pre-war parlor, mahogany | Around $7,500 |
1936 00-18 | Pre-war grand concert, mahogany | Around $10,500 |
1937 00-18 | Pre-war grand concert, scalloped bracing | Around $11,000 |
1940 00-18 | Golden-era grand concert, mahogany | Over $10,000 |
1942 00-18 | Wartime grand concert | Around $9,500 |
1942 000-18 | Pre-war auditorium, mahogany | Around $11,000 |
1947 000-17 | Post-war all-mahogany auditorium | Around $4,500 |
Current market note (2026): clean pre-war small-body Martins with original scalloped bracing have appreciated strongly, and the larger 00 and 000 bodies are especially sought after. Re-braced, refinished, or cracked guitars trade lower, and the all-mahogany 000-17 sits below the spruce-top 18-style guitars. As a buyer, Edgewater prices to the honest, all-in condition of the actual guitar, not the best-case auction headline.
What Drives a Vintage Martin Small-Body’s Value?
Body size: the auditorium 000 and grand concert 00 generally bring more than the parlor-size 0, with the 000 the most sought after.
Pre-war specs: original scalloped bracing (through about 1944) is a major value driver on these small-body Martins.
Style: the spruce-top, mahogany-body Style 18 outvalues the all-mahogany Style 17 such as the 000-17.
Originality: original bracing, bridge, finish, and the interior label matter far more than shine.
Condition: no top cracks, a solid neck angle, and original frets all add up.
Completeness: the original case and paperwork add confidence and value.
How to Identify and Date a Vintage Martin Small-Body
Three things pin down the model, year, and value: the serial number, the body size, and the bracing and style. Here is how to read them.
Serial numbers
Martin stamped a continuous serial number on the neck block inside the body, so these guitars are straightforward to date. Read the number and confirm the year with our Martin serial number lookup.
Body size: 0 versus 00 versus 000
The 0 is the small parlor size, the 00 is the grand concert, and the 000 is the larger auditorium body. Body size is the first thing to confirm, since it separates the models and affects both tone and value, with the 000 generally the most valuable.
Style 18 versus Style 17
Style 18 has a spruce top with mahogany back and sides, while Style 17 such as the 000-17 is all mahogany, including the top. The spruce-top 18-style guitars generally bring more than the all-mahogany 17-style, so confirm the top wood when valuing one of these Martins.
Scalloped bracing and originality
Pre-war small-body Martins used scalloped top bracing, phased out around 1944. Original scalloped bracing, an unaltered bridge, and an uncracked top support the value, while a re-braced or repaired top pulls it down.

How much is a vintage Martin 00-18 worth?
A clean, all-original pre-war 00-18 typically brings strong four to low five figures; Edgewater recently paid $11,000 for a 1937 and over $10,000 for a 1940. Post-war and all-mahogany 17-style examples bring less, and we still buy those.
What is the difference between a 0, 00, and 000 Martin?
They are body sizes: the 0 is a small parlor, the 00 is a grand concert, and the 000 is the larger auditorium body. The larger 00 and 000 are generally more valuable than the parlor-size 0, all else being equal.
