Need a good Suggestion on what to do

[Walter Ezzell]

I have approx 20-30 very old car show plaques. These are the small metal plates that use to be passed out when you attended a car show. These belong to my Dad who has passed and I am trying to think of a good way to preserve them and possibly display them at the same time. Some of these are already 50 years old. Any ideas will be appreciated. Thanks and have a blessed day!!
