So let’s go down the list of some of those currencies:

1. USD ~ is markedly different post breaking from gold standard so 40-50 years

2. EUR - created 1999

3. Russian ruble - post fall of Soviet Union.

I mean what’s the standard here? One way or another maybe the longest running one is the British pound but even then, one can easily argue like with the USD that breaking from the gold standard is a different currency altogether. But if “age” is what we’re talking about, it has to be closing in to what the Euro was at on 2009!
