RARE!! BUSICOM LE-120A calculator

[Gideon Huddleston]

I have this busicom le-120a calculator.

I know it's a rare calculator so I'm wanting to know the price/value of it.

It works fine for the most part, but some of the lines are missing on the numbers.

With this in mind, how much do you think it's worth. And where will I be able to sell it?

Thank you!
