Definition
A term drawn from commercial and administrative usage in Hindostan (the Indian subcontinent under British colonial governance) referring to the discount or allowance granted in the exchange of rupees. Cussore represents the favorable side of a currency exchange transaction — the amount credited or returned to the exchanger — as distinguished from batta, which denotes the sum deducted or charged in the same transaction. The term belongs to the specialized vocabulary of Anglo-Indian mercantile and colonial law rather than to domestic common law or equity doctrine.

Common Confusion
Cussore is consistently defined in contrast to batta, and the two terms are genuinely interdependent: neither is fully intelligible without the other. Batta in this monetary sense is the deduction; cussore is the corresponding allowance or discount. Researchers encountering one term in a colonial-era commercial document should expect the other nearby. Note also that batta carries a separate military meaning (extra pay or field allowance for troops) in Anglo-Indian usage, which has no connection to cussore.

Why It Matters in Research
This term appears almost exclusively in sources touching British colonial administration, Anglo-Indian trade law, and the commercial practices of the East India Company period. Researchers working with colonial-era contracts, exchange transactions, or mercantile disputes arising in British India may encounter cussore in account books, arbitration records, or correspondence that found its way into legal proceedings.
The term does not migrate into American law and has no foothold in domestic English common law doctrine. Its appearance in Black's Law Dictionary reflects the encyclopedic ambition of nineteenth-century legal dictionaries to catalog the full reach of English-language legal commerce, including terms operative in British imperial territories. A researcher finding the term in an American or English legal source outside the colonial trade context should treat it as borrowed vocabulary, not as a term of art with domestic legal force.
The sole primary source cited across all three dictionary entries is the Encyclopaedia Londinensis — a general-purpose reference work, not a law treatise — which signals that cussore was absorbed into legal dictionaries from commercial and encyclopedic literature rather than from case law or statute. This limits its authority as a technical legal term and suggests researchers should look to trade usage and colonial commercial practice for interpretive context rather than to judicial decisions.

Historical Dictionary Support
Black's Law Dictionary (both the first and second editions) and Rapalje & Lawrence are in complete agreement on the definition, tracking the Encyclopaedia Londinensis almost verbatim. None of the three sources adds analytical depth, case authority, or statutory grounding. The definition is transmitted rather than developed.
What the historical dictionaries do not address: the mechanics of rupee exchange as practiced under East India Company administration, the rate at which cussore was calculated, or how disputes over cussore were adjudicated. These gaps are significant for any researcher attempting to reconstruct an actual transaction. The dictionaries establish what the word means but offer no framework for how it operated in practice.
The placement of the entry in Black's (immediately preceding CUSTA, CUSTAGIUM, CUSTANTIA — Latin terms for costs — and followed by custodial writs) is an artifact of alphabetical arrangement and carries no doctrinal connection.

Jurisdictional Note
Cussore is a term of Anglo-Indian commercial usage with no documented application in American, English domestic, or civil law jurisdictions. Any legal significance it carries is confined to disputes arising under British colonial administration of the Indian subcontinent, principally during the East India Company and early British Raj periods.
