hey leave the guy alone.. that's an amazing find.

my guess is one of 2 things......

1. it was an old chinese thing. possibly some sort of gift to your great great grandparents pre-WWII, back when it had it's actual meaning
(peace and prosperous life)

2. You had some family that were supporting germany in WWII, and that was somewhat of a family heirlume created in honor of a german soldier or something of that sort.

that's pretty cool that you came across that... hopefully it's worth a lot of $$
