Tim began collecting sports cards as a kid in the early 1970’s, spending his allowance and any extra money he earned on packs. Since there wasn’t any card sleeves or top loaders, most of his cards were either wrapped in rubber bands or put in photo albums. Tim set up at his first sports card show in 1983 and he was hooked on the hobby. Early on, Tim was both a collector and dealer, which made it challenging to know what cards to hold on to and which ones to sell.

Over the years Tim has worked hard at developing a solid reputation and is recognized as one of the most knowledgeable and experts in the sports card industry. He was one of the first members of PSA and adapters in the grading of sports cards. Over the years Tim became an authorized dealer of PSA and today is known as an expert in sports card grading. We setup and exhibit at over 30 sports card shows annually including all major shows including The National.

Grand Slam Sports Cards was developed with the idea of offering a combined way for the sports card collector to be able to purchase, consign, grade and invest in sports cards. To contact us, send a message over here.
