An oak tree (Quercus sp.) in coins and paper money of Costa Rica (1848-1948)
Bibliographic record
Abstract
In 1848 Dr. Castro Madriz issued the decree which established the Republic of Costa Rica and its new coinage. An oak tree (Quercus sp.) was engraved on silver coins as a symbol of the strength and hospitality of the new Republic. These coins were minted between 1850 and 1862 (1/4, 1/8 and 1/16 of Peso) and between 1864 and 1875 (50, 25, 10, and 5 cents of Peso). This paper provides information on the significance of the oak tree in the socio-political context of mid XIX century Costa Rica. It also provides estimates of the number of pieces minted of each value for a total of approximately 1.871.000 coins. The quarter Pesos of 1853 and 1855 are scarce while the 50 cents of 1875 are relatively common, and all denominations with little wear are rare. The Q. salicifolia tree is similar to that engraved on the coins. After 1880 an oak branch was engraved in different issues of paper money, mainly as a crown for the head of Liberty. The last bill with this symbol was issued in 1943, with a value of 1 colón.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
