  0000474
0000475
0000477 
I can see some additional value of the two consecutive, if kept together,
now all you need is 476 :^) 

This reminds me of a recent ad of a gent looking for his old (70s) HP
calculator, which he had lost years back - he had the serial number and was
advertising for THAT PARTICULAR UNIT.  Now *that* would be an amazing find!
