  • ISA gives the card industry a professional and accurate alternative to the existing graded card market.  While grading companies seem to come and go with increasing regularity (and expensively disappointing results), it is comforting to know that conscientious collectors now have a REAL choice.  ISA is well versed in the full range of cards and memorabilia.  Without question, ISA is a company that is good for this collecting environment.

  • Viable competition keeps all of us working at our best to serve our customers, so the addition of International Sports Authentication should be beneficial to the hobby.

  • Having conducted hundreds of deals with ISA's founder and principle owner over the last decade, I'm confident that he has the hobby knowledge and business wherewithal to meet ISA's customer demands and deliver the same level of satisfaction I've enjoyed in our many dealings together.  We're excited for another firm to enter the market and hopefully bring some much need parity and customer satisfaction to the frustrating process of third-party card grading.

  • Never, and I mean never have I had a better experience with a card grading firm. You guys (maybe gals also) are a class operation. Five stars all the way. Grading was spot on and shipping was faster than a speeding bullet. You've got my business. I will be gone for a couple of weeks, but upon my return I will send you quite a few cards from the 40's and 50's. Keep up the good work.

  • I have compared ISA with other grading companies and have found them to be as professional as any other. They have a quicker turnaround time and charge less to grade cards. I have been pleasantly surprised and happy with the level of service and quality of the workmanship. Try “ISA” you won’t be disappointed.
