What the evidence supports
Two nineteenth-century accounts may describe the same coin, but disagree about whether it came from the river bed or rocks adjoining Castle Rushen and about the discovery date. IOMHER therefore centres its point indicatively in the harbour; this map expands that indication into a 250-metre area rather than an exact pin.
Location and precision
Approximate area · radius 250 m. IOMHER's explicitly indicative Castletown Harbour centre, quantized to three decimal places and shown as a 250-metre area.
Why this public geometry is safe: IOMHER states that its centre is indicative because the historical accounts conflict; the quantized 250-metre area preserves that uncertainty without presenting the centre as the findspot.

Access is not implied
Public harbour context only; this is not a search, waterside-access or ground-disturbance instruction.
Legal note
On the Isle of Man, metal-detector use in a protected area requires written Manx National Heritage consent, and digging or excavation on any land to search for archaeological objects requires an MNH licence. Landowner permission alone is not enough.
Sensitivity note
Public; Historical findspot; Urban redevelopment
