Five Adult Size Belt Buckles never used that I can tell but do show age from handling and storage.

I took detailed photos and explain flaws more within individual description below. Quality, metals and weight of belt buckles vary according to their given style. 

1. Faux Leather Etched Eagle Head Buckle. The hardware on back buckle's metal looks like top layer of its coating is separating from metal. Looks kind of worn in joints and corners - Oval

2. Shiny Gold Full Bodied Eagle with Filigree and Black Negative Space - Rectangle

3. Heavy Full Bodied Eagle with Filigree Leaf and Feather and Black Negative Space - Oval
 
4. Heavy and Rustic "I'm Proud To Be American" Patriotic Freedom Full Bodied Eagle with Classic Standard Shield Shape and Blue Negative Space . Nice details.

5.  Illustrative Eagle Head Buckle on Cream Framed in Gold-Like Metal. On side of the buckle the gold metal coating layer separated from metal. See photo - Oval
