Floral Coin? Medallion? (Id: Medieval Lead Token)

Looks kinda white--is it lead?

If it is lead, I am thinking it may be a wool bale seal.

Lead tokens like yours turn up all over Britain. No-one really knows what they were for; there may have been multiple uses of similar looking tokens. Proposed uses include tavern tokens, game pieces, ecclesiastical or pilgrim's tokens. They mostly seem to date from the 1200-1500 period, though there also seems to have been an issue of local token coinages during the civil war in the mid-1600s. Very few records of their use and purpose survive, as they were not official products of church or state. There is one mention in the records that, during the Civil War, Royalist soldiers would take captured local token coins and melt them down to make lead musket-balls.

The "petalled flower" seems to be a common motif; six petals is common, yours appears to have doubled that to twelve. You can see some examples, on this Worcester archaeological society website.
