There's no formal organization providing one-on-one mentoring for coin collecting, to my knowledge. There's coin clubs, which if they're doing theor job properly can provide group encouragement and education (and most coin clubs only meet once a month), and there's Internet coin forums, which provide a more informal encouragement group.
If you were to ask me "why not", I would answer that I suppose coin collecting doesn't really need "mentoring". There is no One True Way to collect coins, nor even a select few possible options - the field is unlimited. There's general advice, and amongst the general advice is to "collect whatever you like".
The other issue with coin collecting is one of security. Times have changed since the mid 20th century, and people who own a collection of valuables can be a paranoid bunch. A lot of folks who collect coins and who might theoretically make good mentors are going to be reluctant to give out their personal names and addresses to random people, just because they ask for it. This is of course another benefit for asking for help from the Internet; it's much more anonymous.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
