I believe we all acknowledge the JM Price guides as a fabulous reference point, well put together and the major influence on pricing. However, 2011 values have taken a tumble across the board (bar the top end true rarities) since the publication of the 5th guide. Therefore, in order to be a credible up to date guide, I firmly believe that the 6th edition prices need downward adjustment...probably as many as 75% of the titles?
With regards to the 20% UK purchase tax...surely this phrase is only used by the full-time dealers when making their transactions...have you ever heard anyone else mentioning it at a event, "Yea, this is worth £300 in the JM guide, so take 20% off for the tax, so it's worth £240 - oh and it has a pen mark on the label so that's at least another 10% off, so it's actually worth, in accordance to the guide, about £210...call it £200, mate"?
Possibly more importantly, this additional 20% isn't mentioned in the 5th guide at all! Would it not be more accurate to state the valuations not including the 20% extra, especially as these rates do not apply to every country...and Northern Soul collecting is a worldwide phenominum?
An intro page in LARGE PRINT clearly stating that prices are made up from the database, reflect 100% mint condition and any taxes included, would be very useful when trying to explain to fellow collectors/delers that they shouldn't expect £300 for a vg disc with writing all over the label, just because it says £300 in the guide!
Food for thought?
