Can anybody Date this Prayer Token

[Tico14]

Found this Lord's Prayer token around old abandoned church/school today.
It appears to be aluminum, about the size of a quarter.
Philadelphia Liberty Hall on one side, Lord's Prayer on the other.
I'm thinking mid 20th century but don't really know.
Any help dating it would be appreciated.
