I never have found the wallet that suits all my needs -- those with a zip coin section, generally come unzipped and spill coins.  Finally looked for separate coin holder and found this.  Have only used it a few days but so far I love it -- small enough to fit easily in purse or pocket and could stash bills in too if going light ( If it was a half inch wider you could stick a license or credit card in too and carry no purse.)  Works very well so far
