This taxon is often attributed to Acer amplum (or occasionally to A. longipes – see taxonomic note) though it appears not to be true A. amplum as it shows influence of another member of section Platanoidea, possibly A. cappadocicum. It is thus treated here as distinct from A. amplum. A shrub or small tree (4 m after 20 years). Bark green, turning grey. Leaves 5-lobed, sometimes with two additional basal lobes, lobes broadly ovate, apices shortly acuminate, petioles with milky sap (van Gelderen & van Gelderen 1999).
USDA Hardiness Zone 6
RHS Hardiness Rating H6
Conservation status Not evaluated (NE)
Taxonomic note The treatment of this taxon as a cultivar of Acer longipes is likely a hangover from the treatment of van Gelderen et al. (1994), who included A. amplum as a subspecies of A. longipes.
Selected from a large shrub in the Aceretum at Plantentuin Esveld (Grimshaw & Bayton 2009), ‘Gold Coin’ is described as possessing ‘good vigour’ by le Hardÿ de Beaulieu (2003, p. 184). Its new growth is red, turning yellow and then, on older branches, green. In autumn it colours pale yellow (le Hardÿ de Beaulieu 2003). It is grown in both Europe and North America, with examples at collections including The Yorkshire Arboretum, UK, and the Dawes Arboretum, Ohio (American Public Gardens Association 2017).
