The Martin 5K is the Rolls Royce of ukuleles. Classy, exceptionally well built and very pricey. They are the top of the range, made of solid koa and exquisitely decorated.

The most obvious things that immediately show the ukulele to be a 5K model are the flowery design on the peghead and the snowflake and diamond inlays on the fretboard.

The original 5K was discontinued by Martin in 1940. However, they have recently started producing them again. The word on the new models is that they aren't up to the vintage models. Whether this is because they haven't had time to 'open up' as the old ones have, only time will tell.

What is certain is that you are likely to have to pay much more for a vintage model. The current price for a new 5K is $4,199. The price for vintage models varies, but you can expect to pay well into 5 figures for a mint condition model.

Martin 5K on Video

Martin ukes have cropped up a couple of times on Antiques Roadshow. In this appearance, the Martin 5K ukulele was valued at $10,000 to $12,000. It's in excellent condition and I'd say the valuation was fairly accurate.
