How about getting him a framed collection of coins that you have collected for him? You can either purchase rare coins that he may not have in his collection or if you have coins that you have saved over the years, that would be even better! You could also add a personalized plaque to the frame which includes his name and a message from you expressing your love and appreciation for him. Another idea could be to purchase a book on coin collecting or a subscription to a coin collecting magazine which he can enjoy for months to come.
Or you can get him a star map with the date when he was born.
