Alec Posted February 1, 2016 Share #1 Posted February 1, 2016 Anyone have opinion on this? Am I looking at this wrong or should the die be recessed? http://www.ebay.com/itm/WORLD-WAR-1-US-MARINE-CORP-HOBS-2-FOR-MAKING-COLLAR-DISCS-/272117012979?hash=item3f5b7019f3:g:c6QAAOSwnLdWqFBr Link to comment Share on other sites More sharing options...

SgtMaddoxUSMC Posted February 1, 2016 Share #3 Posted February 1, 2016 Alec, I was thinking the exact same thing when I saw the photo... Link to comment Share on other sites More sharing options...
Dozer521 Posted February 1, 2016 Share #4 Posted February 1, 2016 These dies are part of a four die set. They are the male dies. The female dies are the indented dies (or recessed, sometimes called intaglio) which are missing from set. The male dies are put on a ram and the female dies are put on a bolster. The metal to be formed is put between them. When the ram strikes the metal it is pushed into the bolster and creates a metal stamping on both sides of the metal surface. Before the 1950s this was the most common method of creating emblems, buttons, and other military accoutrements. Link to comment Share on other sites More sharing options...
SgtMaddoxUSMC Posted February 1, 2016 Share #5 Posted February 1, 2016 Then wouldn't the rear of the final collar discs have an impression? Link to comment Share on other sites More sharing options...
Alec Posted February 2, 2016 Author Share #6 Posted February 2, 2016 I agree it does not seem right. Link to comment Share on other sites More sharing options...
stucky151 Posted February 2, 2016 Share #7 Posted February 2, 2016 Maybe its a die to make the mold? Link to comment Share on other sites More sharing options...
SgtMaddoxUSMC Posted February 2, 2016 Share #8 Posted February 2, 2016 Hmm that I could see making sense. Link to comment Share on other sites More sharing options...
Schnicklfritz Posted February 6, 2016 Share #9 Posted February 6, 2016 The EGA is properly oriented on the die. So I would assume that this would not be used to make a collar disc since the EGA would be backwards once it was stamped. It couldn't be the right side disc die as the continents would be oriented wrong also for a right side disc. Die to make the mold as mentioned???

Brig Posted February 6, 2016 Share #10 Posted February 6, 2016 Interesting piece. I agree, would have to be used to make the actual dies, not the emblems Link to comment Share on other sites More sharing options...
usmcaviator Posted February 13, 2016 Share #11 Posted February 13, 2016 Alec, These are the hand carved master hubs, engraved on hardened tool steel and used to make the die. Much rarer than the dies I would think. The process of using the hub to make a die, I think is called "hobbing". This one looks to be multi-piece, with the background field being the textured piece and the EGA used after the textured piece to stamp the relief. The dies can wear out and break, but as long as you have the master, you can make more. This is of a known original version of the WW1 EGA collar disc.
