Modern browsers either don't appear to support SSLv2 at all (Google Chrome, Opera 9.52, Firefox) or have it disabled by default (IE7, IE8).
That said, are you concerned about losing business from people using much-less-than-modern web browsers?
Possibly more importantly, are you concerned about your customers' security? Even if they can only connect using SSLv2, do you want them performing secure transactions with you using a protocol that is known to be insecure (see Google)?
As a computer professional, I would not hesitate to recommend to management that SSLv2 be disabled. I would leave it up to the bean counters to determine whether they think the additional income is worth the potential liability.
