The Case statement will already verify if the parameter is valid or not - whether the parameter is int or char. If the parameter is composed of characters, then the Case statement will select the (*) in its options.
Code:
case
1)
2)
*)
esac

If you really want to check the parameter if it's composed of numbers or characters, then use a regular expression.
Code:
PARAM=$1

echo ${PARAM} | sed '/[a-z]/!d'

[[ $1 == +([0-9]) ]] && echo "is a number" || echo "is NOT a number"
