I agree, Peck. The actual price of copper might have a knock on effect with the bulk sale of low grade coins en masse, from any era. It would not explain the current craze for buns. However, apart from the very rare examples, like the 1869, 1875H, and to a lesser extent 1864 crosslet 4 and 1871, collectors are pushing strongly for the very high grades, which have a premium on them orders of magnitude greater than their pro rata value to lower grade examples would indicate. Maybe that's due to their increasing scarcity as more and more find their way into private collections and therefore permanently or semi permanently withdrawn from trade. You could argue that has always been the case, so maybe there is some other factor at work which we can only speculate on ~ or a combination of 2 factors only one of which we can readily indentify. That's a good point. I wonder if the same fever has extended to the commoner dates in high grade, i.e. 1887 - 1893 - anyone noticed? About 15 months ago I managed to win on eBay a 1893 penny with 90% lustre for £77. Recently one with about 20% lustre and some wear on high areas went for £141. Currently there's one with reasonably good lustre but a dark blotch on the obverse being offered for £165 and another similar one but this time with some verdigris spots on the reverse being offered for £225.
