As I stated, there are numerous price guides and other books out there just waiting for you to thumb through the pages. You can get price guides that are very specific to a dinnerware manufacturer, paperweights, ink wells, vintage clothes ... on and on.
Personally, I use price guides as a guideline only. I have found that they are usually pretty steep price wise but it gives you a fair ballpark price on your item. I also purchase old price guides and antique magazines to refer to. They often identify older dinnerware and glassware patterns that
aren't found in newer books. Look through old magazines and catalogs as well this is a wonderful way to become familiar with items from different decades. If you are in the market for good resource and reference books or price guides for antiques and collectibles here are two very good sources for your purchase -
