First two items up show varieties not described by the vendor. This 10d has the constant variety “broken triangle” below the Queen’s head. Why this is not listed by SG is beyond me. Even undescribed, this mint hinged example sold for £55.00. Retail about £150.
This mint hinged 1 1/2d shows a retouched duty tablet at the left side and sold for £32.00. A few years ago I used to pick up items like these two for no premium over a normal stamp. Just goes to show that there are more eBay hunters these days looking for these valuable varieties. However the retail price is still £150+ if you can find one.
Next up is a familiar story that I’ve repeated several times. Crude forgeries like this 5d Board of Education which sell for stupid money (£56.80 in this case). For officials, please, please buy from a respected retailer with a RPS or BPA certificate.
These panes of 20 of the 4 1/2d are fairly common, but very attractive. If you want one, hold out for a perfect pane with no creases and mnh. This very fine example one sold for £206.50 and is the right price. As is the theme of this month, look out for the catalogued plate varieties for extra interest.
And finally, 1/2d control pairs are proving to still be a highly competitive collecting area. This quite common “L” control in mnh condition sold for £31.90. I think that’s more than what a dealer would charge.
