[QUOTE="buckeye73, post: 3292449, member: 93155"]I have been an avid collector of World Coins for over 20 years. Based upon worsening glitches in the NGC/Krause data since about 2015, it is clear that values listed in editions since then should be scrutinized when arriving at the true value of a given coin. Generic examples of glitches are as follows: 1. Catalog values of a few coins are shown 10 times that of an edition a few years earlier. Portuguese India is an example. An earlier edition would normally be the more trusted value unless other references validate the listed value. 2. Conversely, recent edition values are a relatively small fraction of the values from an earlier edition. 3. A column for MS 63 values is occasionally added and another grade column is deleted (F or VF for example). The values listed under the columns are frequently shifted “right” so the old MS 60 value becomes the new MS 63 value as an example. Other similar shifting of columnar values appear to occur. 4. Other random glitches with no logical explanation of listed values. Frank Robinson, an Ancient and World Coin dealer (often mentioned in Coin Talk) indicated in his fixed price lists that he does not trust the more recent editions for pricing World Coins. Frank, or others, please correct me if I misstated this.[/QUOTE]
