Thanks for sharing your excellent photos.

The doubled date looks like VAM-18, and the extra berry on the upper inside wreath top
indicates it is VAM-18 (instead of VAM-19 or VAM-20).

Your coin might be the VAM-18A die state with obverse clash; I'm not sure if the clash marks are there in your photo.

Doubled date like that + strong doubling on O in OF = A VAM 18 sticker from me.
