Interesting to note that both Edward Kann and the Standard Catalog of World Coins (KM) list this pattern being struck in Nickle. It appears that these were struck in an unknown Nickle Alloy rather then pure Nickle. Since pure Nickle is magnetic and these patterns are not, these could not have been struck in pure Nickle.
From the Mas Fera Collection.
With old collector's envelope.
Estimate: $700.00- $1000.00
