Don't be discouraged because you can buy these medals through a catalog. I think the govt. will only replace your medals one time. Maybe an ex serviceman wants to replace his or a sibling wants to have medals also. That is why they have the catalogs. A serviceman or a retired serviceman can use the base exchange to replace their medals at alot cheaper price. There will always be some phony people out there. I think with your silver star you will get a certificate from the govt. That will show your father earned his.
