Creation and distribution of re-strike circulation coins, pattern pieces, and related items.

Research Update
As some members know, I have been digging into the background of Philadelphia Mint re-strike circulation coins, pattern pieces, related items and their distribution in the 19th century. After more than two years the puzzle is beginning to take shape although with a great many large gaps in the picture. Thus far, what is emerging is something less accusatory and self-motivated in actions of Mint employees and officers that generally claimed.
Anyone who happens to have possible pieces of this puzzle is invited to contact me. Full credit and confidentiality are assured.
Regarding INCO and Gould “private pattern pieces,” data collection, photography and preliminary layout are complete and the draft is being distributed for peer review and comment. The completed work is now a 200+ page book with dozens of new varieties and compositions.
Thanks to all for their help!

My personal faves are the patterns that were created for no other reason than to create something cool for the discriminating collector - think 1868 Large Cent patterns.
“Re-strike circulation coins,” not quite sure to what this refers. An example or two?
Normal circulation coins that were re-struck at a later date.
An example or two would still be of interest.
1851 standard silver dollars are one. Multiple pieces in the 1850-55 date range. There are others in the 1840s.
Data collection and review is continuing so I don't want to speculate on other restrike dates and conditions.
