I am so sorry to hear of Don's passing. I wondered what happened to Don's website...I wanted to make a purchase only to find that the site had been taken down. Initially, I thought that Don had retired from the business.
When I first became involved in the paper money hobby back in the 1990s, As a young teenager, I attended the TOREX show and Don was one of the people who helped me to learn about collecting Canadian Paper Money. He always gave honest assessments and advice and this was especially important to me as a young collector.
Doing business with Don was always a pleasure; he always greeted you with a smile and a handshake, and his merchandise was conservatively graded and fairly priced.
If you wanted to sell an item to Don, he was truly "the higher buyer" and he would never put down or criticize what you had to offer.
I can vouch for the fact that Don was more than willing to help collectors; Last year, I participated in an 80's & 90's nostalgia show and I thought it would be cool to give vintage currency as change to the customers. I emailed Don with my request for "spenders" and he came through with flying colours! Don insisted that he wanted to sell me the "spenders" at face value plus a stamp...because he thought that what I was doing was a neat idea!
The numismatic community has lost a gem. I will miss seeing Don at the coin shows. I would like to express my sincere condolences to Don's family and friends. RIP.
