A reader asked:
“In a blog post a few weeks back, you demonstrated how object numbers were created when coins were accessioned into the collection using a combination of date, lot, and item numbers. So why do so many of the objects in the database have numbers that begin with 0000.999.####?”
As we catalogue our collection, we try to identify how each object came to the ANS, but we don’t always have enough information. There are two main clues we use; one is the notes written on the back of the box and the other is the set of ledger books in which accessions have been recorded since 1858.
These three boxes, from a group of French jetons that have not yet been catalogued, show the range of possibilities. The one on the left identifies the accession as 1940.176 and adds that it was a gift of Alexandre Orlowski in November 1940. The one in the center says only that it was purchased in May 1934, but it is usually possible to identify the specific accession by looking in the accession ledger book for purchases during that month. The box on the right says nothing at all about the origin of the object.
Earlier this year I had occasion to catalogue the Society’s holdings of Swedish plate money. Because these cumbersome slabs of copper are mostly too large to fit in our boxes, most of them had no indication at all of their origin. Thus, they presented the same problem as the blank box.
By searching our accession database (a digital version of the ledger books, painstakingly typed into a computer by George Cuhaj in 1981), I was able to identify accession records for plate money, and in many cases I was able to match up the examples in our trays with particular accession records. However, not all accession listings in the ledger book describe the objects in enough detail to identify them. For the plate money, I had three such accessions: 1916.192, “Sweden, 4 plate money” (among other things); 1923.150, “8 Sweden plate money” (among many other things); and 1929.103, “2256 Swedish coins”.
Thus, I was left with a residue of 22 pieces of plate money that had no attached notes and could have come from any of these three accessions. In this situation, our practice is to assign an accession number beginning “0000.999” to indicate that we do not know when or from whom it came into our collection.
