he has at least 36 nickles and 34 dimes (if a nickle is 5 cents and a dime is 10 cents - sorry, I'm not American)
and a maximum of 102 nickles and 1 dime (if he has at least 1 dime) or 104 nickles and 0 dimes
as long as we do not know the number of coins he has in total we cannot calculate how much of each kind he has

There are a lot of correct answers to this question. You don't say how many more nickles he has, just that he has more. So, one answer that was already given, 100 nickles and 2 dimes, is correct, it could also be:
98 nickels and 3 dimes
96 nickles and 4 dimes
94 nickles and 5 dimes
etc. etc.

Cannot be determined from the information given. He could have one dime, or a dozen, and still meet the qualifications.
