I can remember as a 9 or 10 year old there was a 'mission mixture' packet at home. I sorted through it and put all the stamps into their various country types. In there was a block of 6 of the 10c Washington Memorial (Sc #1510) and for a while I regarded that as the most valuable item in my collection!
A year or so of collecting coincided with the stamp boom of the late 1970s. I managed to put together a pretty reasonable collection of Australia quickly as a result of finding an old guy with mountains of stamps who wasn't aware of the boom.
I shamelessly took advantage of his ignorance to put together a collection at no net cost to me.
Around this time, I was at a local trash and treasure market and bought a cigar tin (I still have it) full of postage dues. Within 5 years these were my sole collecting interest.
ebay has permitted the acquisition of a large range of material that I couldn't access otherwise. I now regard dealers as fair game when they don't know the true value of stuff, but I'm a little easier on fellow collectors
