I love my Morgans. I know you will like yours too. I grew up with Morgans and Peace dollars in my pocket as daily experience so Im stuck on them. You can buy many issues in pristine condition for little more than pocket money. Start with the easy to afford Morgans. Most of those are the sharpest strikes and often far mor beautiful than some of the poorly struck rare and costly years and mints. I have 1st, 2nd and 3rd tier albums. The 3rd tier (mostly AU & - and incomplete) are my favorite dollars, more evenly matched in color and 'experience'. My best album lacks only a 1895 to fill the last hole but it may be many years until I can acquire that one if ever. Sadly by the time the pricy coins are broken out and in the album there is too much $$$$$ involved to keep at home any longer so into the bank vault where I cant see them. Its no longer fun when your toys cost so much they have to be locked way. As you look at silver dollars remember its not so much about having them as learning about and hunting for the ones you will remember.
