You've got 54 meters/rangefinders there, plus the wooden tool case. Cheap versions of that case can be had for less than $100, so a decent made one should be more than that. And $10 a meter/rangefinder is $540, so yes, it's a good deal. Some of those meters (BEWI, Prem, and Zeiss extinction type) are collectable to those who know what they are. Any meter in it's original box, and with instruction sheet is even more highly collectable. Folks with viewfinder fixed lens cameras are always looking for rangefinders.
Now if you're looking at buying this collection in order to sell it off, you could realize a nice profit in the long run, as long as the buyer pays the shipping. But then you may also wind up keeping some of the nicer items for yourself!
Go for it.

BTW: I've got a BEWI Automatic C just like the one in the third photo, upper right, and it's still accurate.
