Black leather wallet, possibly camden street, no.16a bus

Left fitness dock gym on camden street, then got the no.16a to nutgrove. I noticed it wasnt in my bag when i got home, It is all black, leather, has an xtravision card in it, a subway card, my laser card, my student card, and a couple other ones, there is only small change in the zip compartment on the left such as 5c and 10c,
