We were referred to Black's when our mum passed away. She was an avid collector of books, and we wanted to get an opinion on the value of some older books in her collection. Adam and Ana came out to her home in Toronto, and were so helpful and diligent and honest in their approach. We ended up selling most of the collection, and consigning a few of the more valuable ones with them. It was sad to see the collection go but we were happy that they will get to good homes. Couldn't recommend more. - Michael & Family
