Ebay has a dealer who sells all the repro's you have shown in your alert.They are located in New Hamshire and continue to offer them as "vintage" "old" etc. Beware of this seller.
 

Are you going to have an area for us to sell and trade our duplicate premiums? I have some to share with other collectors, but am uncomfortable using online auction houses. Being 87 years old I attended night school to learn my basic computer skills.

There are some reproductions that are authorized. For example, the Captain Midnight 1940 Flight Patrol Medal of Membership spinner coin was authorized by both Ovaltine and Skelly Oil at the time of its manufacture. In the Skelly logo, there is a tiny "R" that indicates that it is a replica rather than the original.
