Wow, a double triple wammy! and you know that 4 is the square root of 2, 8 is the triple root of 2, 6 is 3 times 2, and 0 is 0??? ;-) I like it - so I'd keep it - not sure if it's worth more than $1 though
My 7 year old niece told me today that she thinks Twinkle Twinkle Little Star and the Alphabet song is the same tune with different words. Keep it if you like it, no big deal.
Nothing valuable, except maybe sentimental. It's close to being a low serial number, but even if it was it's in too rough of condition to be worth anything other than a dollar
