Honestly, I believe it would be better to sell it for what you can get out of it and then purchase as many Silver Bars and Silver Rounds as possible with the funds and store them away! When the crap hits the fan and it will whether it is war or famine or Oil in the thousands of dollars per barrel, collectible and rare Silver coins will no longer have any intrinsic value above their Silver content. During these times, inflation will hit the roof...paper money and most of the coinage will be for the most part worthless and you will only be able to purchase food, fuel oil and other needed items by bartering with Silver, Gold, Gems and items that others need. Even if I and many, many others are wrong about a "crap hits the fan" scenario, Oil prices will eventually go through the roof, inflation will really be high and Silver...Gold...Platinum and other metal prices will hit values of tens to hundreds of times of what they are at now or have ever been. Also, Silver is the better investment as always has and still tends to gain more value than other metals during rises!
