Very Rare, shiny, and new to me!

My newest Belgian Congo rarity.

1920 Albert I of Belgium nickel Specimen Essai Franc SP66 PCGS, Dupriez 182.

This enchanting coin depicts the laureate head of Albert I of Belgium with ESSAI stamped to the right of the palm tree motif. Virtually unseen in the marketplace, this rare issue presents attractive features and lustrous surfaces, highly-coveted as such. This piece, very similar to the piece that was sold in the Spink & Son 12/17/14 auction. If so they described the coins as follows:

"Belgian Congo, Albert I of Belgium (1909-34), pattern Franc, in nickel, 1920, 12.52g, laureate head left, albert koning der belgen, rev. palm tree dividing value, date and legend, congo belge, essai stamped at 3 o'clock, edge, milled, coin alignment, thick (2.5mm.) flan (Dupriez 182; KM.- )"

One of the most interesting things is that it has a Flemish legend on the obverse and a French legend on the reverse.

PCGS Population = 2. One graded SP65 and this piece which is graded SP66.

None graded by NGC to date.
