20 Drachmai old lettering

Greece introduced this denomination in 1973 under the military junta, but the "old lettering" variety — using the traditional polytonic Greek script — persisted through the transitional democratic period until monotonic orthography was officially mandated for state use in 1982. The distinction between old and new lettering types on circulating coinage directly mirrors the broader cultural argument over script reform that divided Greek academics and politicians for decades.
