Minnie you tell them what you have, they set up an appointment to look at it and pick it up
Can take them in anytime, last time I checked.
If you have many larger items they pick up...but you can take pieces there as well. Quicker to take them in.
They purchase stuff all the time. If you are selling items just call their office and arrange for an appraisal. They will even come and pick it up.
