A beautiful UK 1934 Wreath crown (mintage: 932) (I have one - but this image is from Tony Clayton's site : http://www.ukcoinpics.co.uk/5s3.html)
Here are four Ancient Roman coins with wreaths on both sides, not as the central design, but as a part of it. On the obverse you have a wreath on the Emperor's head, in this case, it is the Emperors Philip I and Philip II (AD244-249), and the other two are both of Emperor Trebonianus Gallus (AD251-253). On the reverse, the Eagle holds the wreath in it's beak. The wreath held by the eagle seems most noticeable on the reverse of the coin of Philip I, the first coin shown. All are Tetradrachmai, minted in Antioch, Syria.
One thing that I find interesting about Swiss coins is that they use wreaths on most circulation coins, that the designs have basically been the same for 100+ years, but that they use different wreath types: wine, oak, etc. Images from Swissmint ... Christian
The wreath on the large size Newfoundland cents have always fascinated me. They are pitcher plant leaves. The small cent shows an intact plant.
Here is a US "Wreath Cent", so called because it replaced the Chain Cent (which was the first regular issue coin ever produced by the US Mint in Philadelphia).
