41-Sigma CS5 Classical Guitar
The market resale value for a vintage 1970s Japanese-made Sigma CS-5 (imported by C.F. Martin & Co.) generally ranges from $175 to $275 USD, depending on condition, setup, and whether a original hardshell case is included.
Price Breakdown & Valuation
Condition / Bundle | Estimated Resale Value | Notes |
Fair / Player's Condition | $120 – $160 | Noticeable cosmetic wear, higher string action, or missing case. |
Good to Very Good | $175 – $250 | Normal light surface wear, good neck/bridge, includes case (like pictured). |
Excellent / Mint | $250 – $300 | Pristine cosmetic shape, freshly set up with low action. |
Key Factors Affecting Value
Made in Japan Label: The label inside the soundhole showing "Manufactured in Japan" with C.F. Martin branding is desirable to budget vintage collectors. Early Japanese Sigma builds (1970s) are generally preferred over later Korean/Taiwanese models.
Current Physical Condition: The guitar appears to be in solid shape cosmetically, though the strings look older/loose. A fresh set of nylon strings and a clean-up will help reach top-dollar pricing.
Hardshell Case: Having a fitting hard/semi-hard case boosts the resale price by $30–$50 and makes shipping easier/safer if sold online.
