Each find needs to have a descriptive report written about it for the Coroner and for the historic record. This report is written by a suitably experienced authority in that type of material; it could be the FLO or a local colleague, or it could be the appropriate curator at the British Museum.
The report should provide an opinion for the Coroner as to whether or not the find is likely to constitute Treasure. It may be that a find was reported to the Coroner as potential Treasure but upon further analysis, the expert feels that it is not.
For many artefacts, it would seem 'obvious' that a find is Treasure, but it can still take a little while for the report to be completed, as it should accurately describe the object and briefly explain what it is. Some finds require more extensive research than others. If the item does not end up in a public collection, this may be the only chance for an accurate record of it to be made.
If the FLO writes a report on the find, it will normally be checked by the national museum curator before being endorsed for the Coroner. If it is felt desirable for a national museum curator to write the report on the find, it will be brought to the museum at the first opportunity.
For finds of coins, it is usually felt desirable to catalogue the coins for the record, but in the case of large hoards and those that will be acquired by museums, a summary catalogue may be produced for the Treasure process. Large hoards from England are often brought to the British Museum for cataloguing.
