I worked in a coin shop for a few years, plus buy and sell coins on ebay occasionally. The new stuff is all "hype", ie: State Quarters, Nickels, and everthing else the US Mint is marketing. I can remember a time when 1970 D Kennedy Halves were a big buck coin but now are cheap. I learned in the coin business that "nothing is rare". All the dates and mint marks are out there, in collections, it just takes a patience and cash to find them, and you can get just about anything you want. Except for the 1909 O Barber Quarter. Tough to find in grades of Very Good and up.
I'd rather my grandkids find a gateway computer box with old tin type photos of Civil War soldiers, dirt road town scenes, and 1900's postcard's from Expositions and fairs. A few old letters from the 1800's that you can get at any Stamp show, and anything early American in print or photos.
Our world is changing with advances in technology rapidly. I believe our present internet generation is experincing a similar transitional peroid compared to the generation of people that went through the Industrial Revolution when Eli Whitney introduced the Cotton Gin that revolutionized the world as people knew it at that time in history.
We are in the infancy of the internet and related technologies. Within 20 years everything we know will be obsolete. The next generations of children will know plastic and "chips" and everthing from the past will be stored in data somewhere.
Now is the time to buy and hold on "old stuff" from 1900's and earlier and pass it on to our grandchildren.
I'm 44 years old. I think back to what was pitched when I was a kid, old baseball cards, vintage MAD Magizines from the 60's, toys, etc., from uncles and cousins that passed it down to me when they discovered the world of cars, chicks, the Beatles, etc. My parents pitched it or gave it away when I got older. I wish I had that stuff now. Especially the Vintage "Lost In Space" Robot that I blew up with an H-100 firecracker in the late 1970's with my buddies while buzzed on 3.2% beer.
