As you are aware, I like provenances. To this end I have a database which I regularly expand with a view to establishing which are the best available examples of a particular type so that when I am looking to purchase an example I know with a good deal of certainty that I am unlikely to find better, or only marginally so, thus negating any further upgrade. Patterns lend themselves to this because they are relatively few in number, so Moore patterns for example have between 100 and 150 known for all types which makes it an easy series to analyse.
This coin being one of 4 examples of P2103 I have traced had the best provenance by a country mile, going back to less than 30 years after it was struck. This was due to Norweb recording the provenance she obtained from Brand, who did the same. Prior to the last 20 or 30 years it was normal for these never to be illustrated or assigned a provenance, usually being made up into bulk lots with similar types if there was more than one example in a collection, so any provenance is a bonus.
So in answer, no it wasn't random. By doing due diligence, it should be possible for me to get an example of the four states of the laureate obverse die, each coupled with a different example of the four reverses (any combo will do), each in a different metal (silver, gilt, white metal and bronzed), which in conjunction with the coronet head P2135 which is only in copper will therefore provide a complete potted history of Moore's pattern pennies (excluding models). The only thing to add to this will be the tin uniface in my possession which was done from an unfinished reworked die that was previously the P2135 obverse, but which disintegrated. It suits my eclectic collecting habits.
The description by Peck for this series also sits at odds with the evidence on the coins, so I am in the process of rewriting this section with a view to an article.
