A trinket for all?

[richsc]

I seem to be attracting a lot of smallish Indian manufacturers' attention due to being nominally in charge of FB RAT. One of them has asked a peculiar question: what trinket could he give to any and all Roman (sorry you others) reenactors? His first idea was a small winged phallus, but I said some might not approve. So if you could have some small piece of swag, what would you want?

[LuciusSallustiusPlautus]

Though it may be out of my period impression, definitely the Roman multi tool found in the UK. But this probably won't fit the description because of its complicity.

Perhaps a small (inch or two high) cast eagle?
A simple phalera with a rat on it?
A period appearing challenge coin of sorts, with the initials of the Latin translation of "Roman Army Talk"?
A distinctive fibula?

An apotropaic Evil Eye amulet.

Being on the barbaric side of things, what about a bracteate, or coin pendant, a bulla would be restrictive on age.
