vintage/antique items that belonged to my 100 yr old grandmother who passed away 7yrs ago...

Hi - I don't think there's too much that can be done with this type of request as there are so many completely different items. The only thing that might be possible would be for someone to recognize one of the items and comment on it, but I can't see how any kind of valuation or history can be given on so many different things. My suggestion would be to put up individual appraisal requests for some of the potentially more valuable items - a watch, piece of furniture or similar would potentially be more valuable than a sink strainer or dustpan so I'd start with those items first. Remember that detailed photos with as much information as possible will greatly increase your odds of someone being able to give you information.
