Sold-listing reading: fair $1,750, good $1,831, excellent $2,234 USD · 3 sold listings (thin sample — indicative only) · as of 2026-10-15. the row is the 'Model 1959S Reissue (100W Lead, 1988-)'; Reverb titles these lots '1959SLP MK II Reissue' (1993 / 2004 / 2000-2017 labels), which is the same reissue line by another name - the raw titles are kept verbatim so acceptance can verify the mapping. The reissue band (1750-2233 USD) is ~6-9x below the vintage 1959 Plexi band (3003-16287 USD, median excellent 16287) - the largest vintage/reissue gap in the whole run, bigger than the Twin Reverb's 3.2x. The 1997 white 35th Anniversary Super Lead was excluded: it is a different anniversary product and heads do not map to the catalog's '35th Anniversary 100W Half-Stack' row. Alignment verified: PRICE DROP marker at the same single position (4) in both arrays. Reverb exposes the price and condition but not the exact sale date, so asof = measurement date; no Fair/Poor sale observed; fair = lowest sold price in sample
