When researching a UK coin, an asking price shows what a seller hopes to receive. A completed sale shows that a buyer actually paid a price. They are different kinds of evidence and should not be presented as interchangeable.
Record these details
- The exact date, design, denomination and finish.
- Condition and any cleaning, damage or unusual features.
- The marketplace, auction or guide used as the source.
- The date of the listing or completed sale.
- Fees, postage and whether the reported price includes them.
Why listings mislead
A listing may remain unsold, be unusually optimistic or describe a different variety. Search results can also mix circulated coins with proof or presentation versions. Compare several like-for-like examples and do not use one exceptional listing as a typical value.
Label the evidence
Use phrases such as “asking prices observed on a stated date” or “completed sales checked on a stated date” when the evidence supports them. Do not promise a figure, give an individual valuation or imply that a photograph proves what a coin is worth.
A practical research route
Begin with the UK coin research method, identify the exact coin and then compare dated evidence. For unusual or potentially valuable collections, consider an independent qualified opinion.
