Found a ring yesterday of unknown origin

[Bill D. (VA)]

Found this water hunting yesterday evening at one of my swimming sites (ring #26 for the summer). It's a wedding band that fits a huge finger, and I haven't been able to decipher the marking. It's marked "TI" with an encircled 12 next to it. I'm pretty sure the 12 is the ring size, but I'm not sure of the composition. I don't think it's titanium, but the only possibility that I can come up with for the "TI" is Tiffany, but don't feel that's right either. Was hoping someone could help with the ID. Thanks!

That's what I initially thought, but the ring was scratched up a bit which I thought was odd for titanium.

Nice find Bill, oh believe me titanium scratches. That what my wedding ring is made out of.
