I have been looking for my information on two similar weights that I bought in August 2008, but so far cannot find the details. I do know, however, that the eBay listing was titled, "A Pair of Paul Ysart paperweight 1980". So I am now wondering ... were these 1980 or 1981?
When I bought my examples, another buyer also bought two. There may have been a few others available at the time from the same seller. I have since seen at least two on eBay again in more recent times, so perhaps some of the first items sold were put out for sale again?
Anyway, they are very good weights and most (or all?) had a mix of Paul Ysart lampwork with Caithness millefiori canes and a Caithness "Peat" ground. My examples are not faceted.
