Early serial numbers - 27S


Hi All,

I just got a 27S MIB with what appears to be an extremely early serial number based on what Mier-Jedrzejowicz's book and this web site say. It's serial number is: 2747A00209.

I usually don't pay too much attention to them, but this was in such perfect condition in such a faded box that I checked it. Do any of you consider early serial number calculators to be worth more than later ones (assuming that there were no model variations)?
