I was wondering what the other set of numbers on a brick were for?

For example, on a lime green 2x4 brick (randomly pulled from a bin I'm working
through) there is the seriel number "3001" which defines what piece it is.

Then, in the other corner is another set of numbers "6-251"

Is this anything useful to us sellers? Is it just something to do with the date/factory/machine
it was manufactured on?

I don't suppose it tells me what colour the brick is? My word, that would
be so helpful! Telling medium blue from maersk blue or dark pink from magenta
isn't always easy!

Number of the mould and position of the mould part this brick was made in.

It's useful for a few collectors, who collect special bricks and/or very
old bricks (mainly 2x4 test/prototype runs in most cases) also based on the mould
number and mould position number.
Not for the generic modern brick, though.

  Is it just something to do with the date/factory/machine

Date: No. These numbers are part of a mould that will be/has been used for years.
Location: Yes, unless this mould has been used in multiple locations (happened
for old moulds sold/sent to other manufacturing sites back then)

Hehe, unfortunately not... The same moulds are used for all colours.

Hi Jan,

Wow, that was really helpful! Thanks for sharing your knowledge with me If
only there was a way to guarantee the actual colour of the brick you're selling!
