Silver Dollars come in many different varieties and date back to the late 1700's.  Silver dollars are highly collectable and range in their value from $15.00 to upward of hundreds of thousands of dollars based on the rarity of the coin.  When selling your silver dollars, it is important to work with a company that is going to educate you on what you have and pay a fair price for it.  The transactions be a win win for both the selling party and the buying party.  When choosing a company to deal with, make sure to thoroughly check the online ratings of that particular company.  A company that is not treating people fairly will be given negative reviews.  Although it is impossible to please every customer that walks through the doors of a business, you want to pay attention to the trends of the reviews.  If you consistently see threads of negative postings, you might want to consider working with a different company.
There are may collectors that specialize in collecting Silver Dollars.  I believe that we are simply caretakers of coins for a period of time.  We make sure that the coins we purchase, are put into the care of collectors that have an appreciation for the coin as well as its history.
