Vintage wool crocheted mini bag/coin or mirror purse with mirror!

Found this in one of my grandmother's purses. Great colors-black, olive, lime. Mother of pearl button and self loop. The tiny mirror is just a bonus "Dobbie" which was an accessory store years ago! Mirror is a bit worn. Pouch measures about 3 7/8" x 3 1/2". Guessing it's from the 50's?
