In 1958, Gibson began producing the Les Paul Standard model, which retained most of the features of the Goldtop, though the finish became a cherry-red version of the Sunburst finish long used on Gibson's flat-top and archtop acoustic and hollow electric guitars. Production ended in 1961, when Gibson redesigned it to feature a double cutaway body, subsequently becoming the Gibson SG. Around 1,700 instruments were made in the first series, and these are now highly valuable. Though it had no remarkable provenance, the pre-auction estimate of $225,000 to $250,000 for this guitar proved accurate. Production was resumed in 1968 due to public demand, and continues to this day. It sold for $237,000 at a Skinner auction on 3 May, 2009
