Bombay Presidency's tin pice occupy an awkward position in Company coinage history — tin was a compromise metal, cheaper than copper but prone to oxidation and physical degradation, which is precisely why so few survivors exist in collectible condition. The Bombay mint during this period operated under a patchwork of local contracts rather than centralized Company oversight, and die consistency suffered accordingly.
KM#156 spans over five decades of issue, meaning examples can vary considerably in execution from one decade to the next — not as named varieties, but as the predictable result of changing contractors and worn working dies never formally retired.
