At the beginning of Better Call Saul S2E04, we see Mike sitting on his couch, admiring some kind of golden boxing gloves charm.
And then, later in the episode, when Mike confronts Tuco Salmanca, Tuco is shown wearing the exact same boxing gloves charm, except it's silver.
Mike and Tuco get into a fight, and Mike grabs Tuco by the shirt (near the charm) but Mike never rips Tuco's necklace off.
If Mike never took Tuco's necklace, and if the two charms aren't actually the same (silver vs. gold), then, can someone please explain what's going on?
Why do Mike and Tuco have the exact same charm, just different in material? What's the meaning behind this?
On the off-chance that the two charms are in fact the same, and Mike recast it gold, then how did Mike get Tuco's necklace? Why would he even want it?
