Post a Pattern

Droz pattern halfpenny restrike, Peck-991.

Recently arrivals: Romania 1930 20 Lei Pair, both London mint proofs, both ex-Pretoria mint museum, both very rare, only 2 known to commerce, possibly another in the Royal Mint Museum (collection not searchable). These were struck at Paris, Heaton, KN, and London (no mm). IMO, for non-Commonwealth issues, silver proofs of record from this period were saved by VIP recipients and turn up about once a decade, but minors were ignored/spent/trashed and are not to be found.
Mihai I KM50 PCGS PR65. The only other recorded example (ex-Melbourne mint though not noted by NGC, spotted NGC PF64) sold for 1000 pounds hammer London coins 2017, a respectable but not the most visible venue.

**Carol II KM51 PCGS PR66. ** Only other example I could find was a heavily spotted NGC PR63 ex-Melbourne sold by DNW. A Paris mint 10L, still rare but obtainable in PR67 hammered $1500 HA.

Egypt. Rarity. Paris Mint proof of the new type (smaller diameter, no flower right of toughra) 10 Qirsh silver AH1277/4 (1863), and a one year type for all denominations with this design. Gem proof with deeply reflective surfaces & cabinet toning: excuse the poor photography.
Minted while the French were trying to build the Suez Canal before the period of British domination. The only other pre-1916 Egyptian silver proofs of any date or any denomination that have been recorded are either Berlin (W) or Heaton (H) mint. However, Paris Mint proofs of base metal para 1277//4 exist and do turn up. 1277//4 gold coinage is extremely rare but recorded though in business strike only. This coin was examined by Joe Lang of Stephen Album who validated it as a proof/pattern and said it was the first he had heard of or seen.

This one got me started on Egyption Proofs years ago, especially neat IMO:

I think it's fitting to post my new acquisition to this post by @Stella since she was the one who allowed me to view this HK Sale coin in the NYC Heritage offices.

NGC MS64BN. 1899 (Meiji 32) 5 Rin pattern, ex-Jacobs. This was a Meiji pattern that was ultimately issued under emperor Taisho in 1916. [NB: Jacobs obtained this coin in ~1945 and it was most likely red at the time. Unfortunately, his SDB was subject to moisture at some point and many of his copper coins got this somewhat dingy look to them. It's not that bad in hand, and there is no actual corrosion. It certainly matches my other Jacobs patterns of the Taisho era.]

Thanks @Stella! Your efforts were not for naught!

Edited to add: 1 Rin = 1/1000 Yen

Just back from the beach. Love the toning. One of my very favorite coin designs. The silver version was the first circulating crown of the world struck on a steam press. Matthew Boulton and James Watt took a money-losing order from the Sierra Leone Company for only 800 $1 coins in order to showcase the quality of their product.
