A 1998 Washington quarter. Let's say that coin is NGC MS67. Assuming the world is still civilized and the people in it tend to have interests similar to ours and assuming our dollars are equally as valuable as today, at what point would this safely tucked away coin become worth $300? According to NGC, a 1998 P MS67 is worth just under $50. On the open market, who knows what it'll bring, maybe $30? I ask this because Ive heard many investors, not just those numismatically inclined, that the best time to buy is when people aren't interested in that particular item. Doesnt mean you buy chewed chewing gum, just that you're sort of a contrarian and you buy in an area that is and will likely remain popular but you strongly consider those particulars within that area/sector that aren't inflated by buyers. Are coins such as the one I cite above poised to 'pay off' 10-30 yrs from now? And aside from that coin and aside from any investment talk, at what point do you think the higher grade coins (AU to MS65) that are now being minted will be worth a 'lot' (however you wish to define that)? I know nothing about ancient coins, but from what I've seen it seems their prices are a LOT lower than what I would've guessed. Are, for example, today's Morgan silver dollar destined to wane in value hundreds of years from now when our civilization is upon the ruins of others? I know there exists some priceless artifacts, but it seems theres a good number of old coins that have surprisingly low value because they lack an educated buying base.
