The Lb. avd. price implied here is $66., the "low" of "$5.49" is presumably a NY Spot for ore at the intrinsic weight. The difference between Scrap and Intrinsic may also imply the average commercial refining cost per Ozt. 

1880: 1 Troy Oz. platina (NYC: Imported ore, 82.5%?) = USD$ 4.53
1880: 1 Troy Oz. Pt (NYC: Imported ore @ 99.9%) = USD$ 5.49

1880-4:
The stabilization of the US currency (par with Gold) coincided with the lowest retail/ catalogue price for Platinum manufactures in the post-Civil War period. According to prices in Meyer's Catalogue, manufactures were offered at advertised rates not witnessed since the mid-1850s. (Individuals may still have purchased those items at a greater discount through schools & universities.)

This Retail Low is especially peculiar as speculator attempts to corner the market caused a platina price spike (worrying dentists and industrialists) in 1879. Periodic declines, oversupply at port cities and discount events may also have occurred in some markets.

Otherwise, the general US retail Low appears to have occurred about 14 years after the Russian liquidation and 21 years decades after the absolute platina Low of 1861. Refined Platinum prices hovered at these rates for a couple of years.
