“It is a pleasure to highly recommend ABC GT Coins! Absolutely one of the best experiences EVER meeting and doing business with Gary. Communication was prompt, clear and supportive. Exchange rate was the best on the island. And BEYOND that Gary is one of those people you meet in life that is one of the good guys. He’s the real deal. I feel like I met a long lost friend and came away better for the exchange. That is talent, that is genuine precense, and a lifetime of skills all rolled into each step of the transaction. One of the best examples of island ALOHA! Mahalo, Darcy”. Darcy B.

“Gary is very great person and very trustworthy if you ever need to sell your coin collection. He will take the time to explain the worth of your items and will give you a very reasonable price ( top dollar) which is a lot better than some other dealers. He doesn’t rush or pressure you. I would definitely go back to him in the very near future to do business with him Mahalo Gary”. Andrew N.

Gary took the time and came out to appraise the coins he and I had discussed over the phone. He was very knowledgeable as we went over the coins. His extensive knowledge just made everything easier and less complicated in its entirety. He was up front and to the point. I would highly recommend him”. Jennifer T.
