Guide snapshot checked 23 September 2026. These are Key Collector raw acquisition estimates, converted from USD at GBP1 = USD1.3348 (Bank of England reference, 22 September 2026) and rounded to whole pounds. Low, Mid and High are the provider's broad condition bands, not numerical grades. They are not verified UK fair-market values, current offers or an appraisal of your copy. Fees, postage, taxes and currency-conversion costs are excluded. The date records our check, not the date of an underlying sale. Use the source link and recent comparable sales before buying.
