when considering transmissions from earth - one must take into account the " inverse square rule " for signal strength // propagation .
follow the external linksa or google to learn more
the TL : DR summary :
historic broadcasts are still " out there " - BUT even if " something " is scanning the correct part of the spectrum - the chances of them recognising it as a signal is remote - theres a lot of noise

Well, my Mom's collection (which I inherited) was just appraised at about $940,000. Needless to say, those stamps are in that collection also! (along with just about every other US Stamp ever minted).
