TIMOTHY GRAT OF THE MOFFATT MINT ON BROCKAGES

In response to our recent discussions on brockages, Tim Grat of the Moffatt mint submitted these thoughts. -Editor
I wanted to chime in on the brockage discussion...I believed one of your readers would come to the rescue of the query and describe the piece correctly. And while I was happy to see my good friend Mike Ellis, the premier authority on errors in my opinion (despite the follow statements!) come to the front, I am afraid I must disagree.

The description Mike gave indeed covers the first steps in the creation of this error, including in my opinion its "helped" nature. However, this piece is one more step in the progression described.

Simply put, this piece is the brockage of the coining error Mike describes. This is evidenced by the lettering being in reverse... I would call this a "Brockage of a Double Struck Retained Indent"

I have attached an image to show the progression of the pictured coin...including the "gorgeous brockage on an undersized planchet that would fit with Bill's coin as snuggly as two pieces of a puzzle!" ...as Mike put it.

Double Struck Indent Counter Brockage


  • Step 1 - Coin is struck and stays in coining chamber for whatever reason.
  • Step 2 - Smaller planchet inserted onto struck coin and struck again
  • Step 3 (Bill's coin) - Third, full size planchet, inserted onto double struck retained indent, and struck again!


Thanks for the follow-up and image; what a great error! -Editor
