10,000 stamps (all from that era).
90% of those were contained in blocks of 2 to 120 which I will slowly post if you are interested.
Back in 1994, AFTER the 'crash', the collection fetched some £375,000 ($700,000).
If sold now, it would probably be £3m. I kept the scans archived away all these years in the hope of one day doing something with them, knowing I was the first and only person to ever complete the 'printing research' for the issues, and as the collection went to several hundred different bidders I doubt it will happen again.
Up in my loft, in a large binder, I still have the printers records.

Segments of the collection, which i would show later, won a number of gold medals. In fact one collection I bought complete whilst compiling my own was a gold medal winner several times in its own right.

I just also realised that also have scans of my prior collection, which also won awards, which was of George V issued stamps, and included every known printing of the rare 'Seahorse' high denominations.
