The Misfiled Coin Hoard
A regional museum holds 214 silver denarii reportedly found together beneath a villa floor in 1968. The accession register lists only 'hoard, Roman, 3rd century'. Three problems surface. First, 41 coins bear the portrait of a ruler whose sole reign lasted less than three years, yet the hoard is dated a century later. Second, the coins' wear patterns fall into two clusters: 60 show heavy circulation, while 154 look nearly uncirculated. Third, the excavation notebook was lost, and the donor was a dealer who acquired material from several sites. The curator wants to display the whole group as 'a family savings jar buried in a crisis'. A local newspaper has already run that story. You are asked to advise before the labels are printed.
1. Identify the two most serious evidential weaknesses in treating these 214 objects as a single closed deposit, and explain how each would change the interpretation.

Weakness 1: no secure archaeological context. The only provenance is a dealer's report and a lost notebook. A closed deposit requires that the objects entered the ground together and were not disturbed. Without stratigraphy, a site plan, or a container, the assemblage could be a dealer's mixed stock. If so, the group tells us about collecting and trade, not about one household's savings.
Weakness 2: internal inconsistency of wear. Sixty heavily worn coins and 154 near-mint coins behave differently. Coins circulating for decades before burial should show comparable wear unless they were curated as keepsakes. The near-mint majority suggests either a later addition or a separate parcel. If the group is mixed, any 'crisis burial' date must be argued from the latest securely associated coin alone, not from the whole lot.
The dating conflict with the short-reigning ruler compounds both problems: it shows the register's '3rd century' label is an assumption, not a measurement.
2. The newspaper story is already published. Recommend what the museum should do with the display, and justify your advice in terms of how historians handle uncertainty.

The museum should not print the 'family savings jar' label. It should display the coins as an assemblage of uncertain origin, with a short panel explaining that the findspot is unverified, that the group may be mixed, and that the burial date is contested.
Justification: historians distinguish between evidence (the objects and their documented context) and interpretation (the savings-jar story). Presenting interpretation as fact misleads the public and makes the museum vulnerable when the claim is challenged. A better display states the competing hypotheses - single deposit, mixed dealer lot, or several parcels - and shows what evidence would decide between them, such as metallurgical analysis, die links, or recovery of the notebook.
Correcting a published error is not embarrassment; it models how knowledge is revised. The museum can note the earlier news report and explain the revision, turning a problem into a lesson about source criticism.
