Lucky man. Presumably this is post-1970, so presumably has still some security value. Just what, would be a matter for your insurer if you wished to use it.
As a matter of economics, I guess there would be less interest in a deposit safe than a normal free-standing safe. Usually, safes are difficult to sell because for most would-be buyers, moving costs more than most are willing to pay to acquire ownership. Also, if this is removed, there will be the cost of making good the wall. Just painting over the deposit drawer and leaving it could be the simplest and cheapest course, unless there is a good reason for removing it.
At the least, probably the locks and safeplate could be sold off to collectors.
