Is there really treasure in your attic? Research collectibles and antiques through the Fine Arts and Music Department.
Determining what an object is and what it was used for gives you a better chance of understanding its importance, rarity and value. Here are some questions to ask:What does this object do?
Learning how an item was used can help to identify and date it.
In this video, the woman is playing what looks like an old radio, but it’s really a Theremin, the very first electronic musical instrument. Antique radios are sometimes valued in the hundreds of dollars, theremins in the thousands.
The antennas on either side of the Theremin create an electro-magnetic field. The Theremin is played by distorting this field, and moving one's hands in the air between the two antennas.
What is it made of?
The material an object is made of can help tell its age and value. Some plastic jewelry is collectible. Bakelite jewelry looks like plastic but may be worth more. Simple tests can tell the difference between plastic and Bakelite.What is its history of ownership (its ‘provenance’)?
Tracing the ownership of an object could help you determine when it was made, by whom, who has owned it in the past, and maybe something about its value.
