Nature of the beast, when selling everyone is looking for a bargain, it's well known your money is made at purchase, that is unless you plan on keeping certain bars or coins for the length of time needed for appreciation. In my exp buyers always want something for nothing, remember that as we are also buyers and we know at which point money is made. A good example is maples, fall for the 9999, and you may be sorry, people mostly know about the affinity of these coins for spotting, yet you still pay a premium for these coins, I fell for it as many have. Fortunately for me mine went straight from coin tube into airtites, I don't have spotting yet and they are a year old. My storage solution maybe helping in a de humidified safe, from what I have seen though it may not be relative as it seems to be a chemical reaction on the surface of th Ag. At the end of the day it's all about the Benjamin's so research buy in bulk and sell small lots or individually, eBay for sales, well some might but figure your PayPal and eBay fees into your sale price. Even if you wait for Ag price rise short term, you will find yourself selling for what you paid from dealers unless you can buy bulk. For me it's long term so I am not bothered. Even for people like me buying and refining you will find scrap sells for premiums above spot unless you do plenty of networking, pre decimal silver also has the same dilemma in Australia so knowing your coins and retail value of them makes a huge difference, quite often you will get more for the coin so some are just not worth the time and money to refine. It's a crazy market at times and takes much experience to learn the ropes of successful buying if your course of action is to short your stack within a definitive period of your buy. Nothing comes for nothing and the knowledge and wisdom in buying and selling is worth $$$ in itself, un allocated is cheapest, but you will need a substantial investment to make it work and worth your time. Best of luck, research, read, find a mentor, exercise great patience and you will find yourself on top of the beast instead of under it.
