Quantities of historic clothing are also missing. These include 40 dresses, 24 skirts, 11 belts, 10 coats, four waistcoats and three underskirts.
Outcalt said clothing and textiles used to be kept track of much more informally by museums than they are now.
"They weren't understood in the same way that we understand collections of objects today. People could bring in, say, bed hangings and then repurpose those bed hangings to cover a chair. Sometimes historic textiles were repurposed to incorporate in decorative arts rooms and the like."
The list of missing items includes a number of objects that may have Indigenous significance, such as four wearing blankets, three moccasins, two headdress fragments, two kamik boots and two worked bones, as well as a wampum, wampum string, rattle, parka and toboggan.
The items’ object numbers show some batches of missing objects were acquired at the same time.
Most of the now-missing oracle bones were acquired together in 1931, while a group of 21 missing photographs all arrived at the museum in 1940.
TorontoToday requested further information on 30 missing coins from the museum's collection.
These turned out to include a group of 19 coins found in an archaeological dig in Jerusalem, studied in 1985, but found missing during an inventory conducted in 2014.
"We're talking less than $20 per coin," Outcalt said of their value. "These are very, very common. In terms of the concerns around this being something going on to the black market, that's unlikely."
A 17th-century Japanese coin in the inventory of missing items could be more valuable, however.
"That is something that we need to explore further and will — but it's really hard, because there's very little documentation on it."
