I bought this book with the idea that it would be a valuable resource for me when I sell some of my collectibles. While I did find most of my items and the current market value is there for me to sell or get insurance, the one thing I needed most was the issue price. I have no clue as to what I paid 25 years ago. No one thought to keep receipts back then. Since these items are considered collectible, IRS regulations require that it be reported on Schedule D and you pay tax on the gain. If you have no idea as to the cost, you end up paying tax on 100% of the sale price! Who wants to do that!!! If this book contained the issue price, that could be used as a cost basis.
