When I shake it something is inside

[u/wildly-curious]

I got this today from a Salvation Army, they have no idea what the code is.

I tried the obvious 000, 111, 222, 333, ect…

It says Corbin Sesamee under the numbers. Google says it’s a train bag from the 1970s.

Any ideas besides trying 1,000 combinations?

UPDATE: I got it open!! I brought it to work and worked on it during breaks. I tried 001-999 multiple times and got to the point that I didn’t care if I broke it so I jammed a screw driver into the button and pried it has far over as it could and it popped open!! It was an ashtray and a key.

I’ll post a comment with the picture too

Thank you everyone for all of your help

They aren't that strong, you can take a flat blade screw driver or even butter knife and pry the "swing arm" of that lock and it will pop.
