Condition for most Fleming collectors is paramount, even the later Bond titles in the Richard Chopping dust-jackets can vary wildly in price depending on condition, and the market has become increasingly fussy; compared to 10-15 years ago, browning and moderate age wear to '60s era jackets can now see the value drop to a tenth of what a committed collector might expect to pay for a truly superb example.
In regard to the earlier James Bond first editions, especially the first three titles, finding them in very good+ condition is very difficult, often resulting in collectors accepting copies with some wear to jacket extremities, price-clipping or similar; some collectors prefer to get such jackets restored professionally where possible, though the trend for this goes up & down.
The difference in price can be surprising, Moonraker for example is notorious for dulling to the flame pattern on the jacket, especially at the spine, and as a result genuinely bright, unrestored or tampered with examples can exceed £12,000, even at auction. Compare this to the £5,000-£7,000 you might expect for what would still be otherwise considered a 'very good' example with the usual dulling to the colour and you have an insight into the difference condition can make. Truly exceptional copies of Casino Royale can fetch over £60,000, compared to the c. £30,000 you might pay for a very good, unsophisticated example or a copy with skilful restoration resulting in a copy that still presents very well.
