I'm often asked,  "Why do people sell their first edition copies of the Book of Mormon to you?"  Although there are a variety of reasons, the most common is for financial reasons.   In a generation, this iconic book has increased in value from $100 in the 1960s, to $5,000 in the 1980s; and now a copy was appraised for $100,000 on the "Antiques Roadshow": http://www.deseretnews.com/article/865593827/1830-first-edition-Book-of-Mormon-appraised-for-100000.html  and I've  just listed another copy on eBay for $79,995: http://www.ebay.com/itm/291060578422?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
