With a thorough understanding and liberal application of Murphy's Law, I believe we can all save vast amounts of time and effort when searching through coins. Murphy's Law, as applied to coin collecting: only the worst condition coins in a given lot will be particularly interesting. Good dates, doubled dies, overdates, etc. will *always* be the poorest condition, if present. The higher the potential rarity or value of a coin, the worse the condition will be. I swear to freakin' god... in a lot that is 90% MS, the rest mostly uncirculated, it is the one truly good coin that would grade at a 10 or 12... *fml*.
Murphy's law in coin collecting: I buy zero 2015 platinum coins and they go through the roof. I buy 4 this year and they flop.
There are other corollaries for example After really stretching for that rare coin you haven't seen in any condition for years, three more pieces in better grade at lower prices will appear the next week.
Are they flopping? Haven't looked but I thought they were up to $2k+ on ebay yesterday. Thought it was an under hour sellout. Mintage too high I guess?
Recently I had three very_nice coins on my Watchlist on Ebay awaiting the day I'd have money in the bank to buy them. They sat still, waiting for me, for ten days. I last checked at 11:30PM on the day before I could purchase them, and limited myself to 4-1/2 hours' sleep that night so I could be awake at 4AM when the money was deposited, to make the purchase. They disappeared in that 4-1/2 hours.
