How do I tell if a WWII helmet or medal is real?

Reproductions of WWII helmets, medals, badges and insignia are widespread, so careful comparison matters. On a helmet, look at the shell, the liner, the chin strap and the hardware. Original helmets often have markings or heat lot numbers inside and period construction details, while fakes may have wrong rivets, wrong strap materials or fake aging.

With medals, look at the metal, the weight, the quality of the striking, the ribbon and any maker's marks. Originals often show crisp detail and natural wear, while reproductions may be lighter, softer in detail or oddly aged. Engraved names can add value but can also be faked, so documents that back them up matter.

Compare your item carefully with documented examples in military collecting references. Be aware that rules about buying and selling certain medals and decorations vary by country and state, so check before selling. A military collectibles dealer or appraiser can authenticate the item, which is wise before you buy or sell anything that seems rare.
