Since you've got nothing better to do: The 1663 Petition Crowns of Thomas Simon

Weiss

HA's got a PCGS-graded example coming up for auction in April. Hadn't heard of these pieces before (I know, right?)
tldr: Chief engraver under Cromwell was demoted when Charles II regained the throne, though he was apparently far more skilled than his Dutch competitor. He submitted patterns to prove his worth and, on their edge, petitioned Charles II to reconsider and reappoint him. They are considered to be the most important British patterns and some of, if not the, most sought-after British numismatic pieces:

One of Simon's 'Petition" Crown's was on display in Colorado Springs at the ANA Money Museum when I visited.

That example had a two line inscription ""THOMAS SIMON MOST HVMBLY PRAYS YOVR MAJESTY
TO COMPARE THIS HIS TRYALL PIECE WITH THE DVTCH AND IF MORE TRVLY
DRAWN & EMBOSSD MORE GRACE; FVLLY ORDERD AND MORE ACCURATELY
ENGRAVEN TO RELIEVE HIM"

The words engraved and arranged in TWO numbingly detailed rows.

Former forum member @SwK owned a Petition crown. I don't know whether or not it was the one that was on loan to the museum when I visited.

An interesting historical footnote regarding Simon's replacement is that not only had he been aligned with the anti-monarchists but, also, the newly appointed Dutch chief engraver of the Tower Mint's parents had loaned Charles money while he was on the continent.

The copy owned by the Royal Mint Museum is on display at the old mint spaces in the Tower of London. I saw it last October.
