10 Pence - Elizabeth II Puffin

Guernsey's wildlife coinage series has long favored the Atlantic puffin, a bird that once nested on the island's rocky outcrops before mainland pressure and changing fish stocks pushed colonies further north. The 2021 issue continues a denomination pairing that stretches back to Guernsey's decimalization in 1971, when the puffin was selected over the heraldic imagery favored by the other Crown Dependencies.

Nickel plated steel replaced the older cupro-nickel composition as part of a cost-driven retooling common across British isles coinage in the early 2010s — Guernsey followed the Royal Mint's lead rather than acting independently on that change.
