There are more questions about the whereabouts of items thought to be under the safe-keeping of the Boston Public Library.

A library spokeswoman says a retired employee who now volunteers told administrators last week that gold coins originally placed in the cornerstone of the main building have been missing for decades.

The coins were apparently placed in an 1888 time capsule that was opened in the 1990s. No estimate of the coins' value was disclosed.

A library spokesperson said based on his information, it's believed the coins went missing decades ago.

"The Mayor was made aware on Tuesday during his meeting with Amy Ryan and Jeff Rudman. The Mayor is very disappointed in yet another breach of security," Mayor Marty Walsh spokeswoman Laura Oggeri said in a statement.

Police and the FBI are investigating the disappearance of two pieces of artwork worth more than a half million dollars combined. A top employee has been placed on leave.
