Mack Bulldog Lapel or hat pin pair. One appears to be pewter, but is not marked in any way except for the “MACK”, on the collar. Detailing is sharp and clear with no apparent wear and no damage. Number two is a gold-tone, as in brass? Or, actual gold? I have no way of testing and so if it were to end up so, my loss your gain, but is probably brass. Number two marked same as pewter, but has better detailing, or maybe just shows better due to coloring...
