Any antique'ers?

That’s a blue tint glass Ball mason jar made between 1923 and 1933 with the tin/zinc lid. The lack of an underscore on the Ball logo establishes the date. They are generally worth between $15-30 depending on condition. Low and high goes about $5 beyond that range.

I figured they were worth more than that lol. It was my grandfathers get had a whole bunch of them and when he passed my dad went thru and got all his stuff. I managed to find this one hidden in a corner and it's a number 13. I always heard 13s where hard to find because the old timers thought that they were bad luck and would throw them out. Idk if that's true?
