Klaus Hasselmann shared the 2021 Nobel Prize in Physics for his work on stochastic climate modelling — specifically, his 1976 development of a model linking short-term weather variability to long-term climate change. Ghana's Nobel laureate coin series, issued through the Bank of Ghana in titanium, is an unusual programmatic choice for a sub-Saharan central bank, with most such commemorative series historically dominated by European and Pacific island mints chasing the collector market.
Titanium at this specification is notoriously difficult to strike cleanly, and surface inconsistencies on these issues are a known production characteristic, not damage.
