Few years back I bought 3 numbered purple hearts from three different people. All were numbered 4XX,XXX on the right side instead of the left side. The numbering would have put them to be Robbins contract. The numbers are aligned and done very well. The edge of the medal is thin enough so that the smaller numbers seem to run from edge to edge, penetrating the edge. The edge is not more than 1.25mm. Recently someone made a comment about how thin the medals were that got me curious. Here are two numbers. I just wanted to find out if I have been had or are they typical.
I also used the 160 XX
