Did you try to match the mark in a subsequent rule and LOG the packet when the rule hits?
See also man iptables:
mark
This module matches the netfilter mark field associated with a packet (which can be set using the MARK target below).
--mark value[/mask] Matches packets with the given unsigned mark value (if a mask is specified, this is logically ANDed with the mask before the comparison).
