Six months ago I got some simple business card made up with my name, phone, email address on them. They were something like $19.00 for 500.
Now when I am asked by people the often asked question "did you find anything?" I am polite with them and show them my finds. Then hand them my card and tell them I will hunt their property and split the finds.
One of the first things I did after starting in the hobby was have a set of "business" cards made - in my experience, wisely used cards can be a huge asset while requesting permission on private property, or for establishing a network of potential permissions.
When door knocking/cold-calling, I think it creates a certain level of credibility for what is otherwise a pretty odd request - we are asking someone to allow a complete stranger to dig little holes all over their lawn, after all
Plus, I think it also helps to generate some trust: I have my home address on my card in addition to my other contact info - in my mind, if I know where they live, they should know where I live. Along the same vein as trust, I splurged and had double sided cards printed, using the back to list my version of "the code of ethics". It serves as a reminder to them that I intend to fully respect their property.
But the greater value of cards may well be for building up a network of potential permissions. Like MaxxKatt said, anytime someone approaches and asks "found anything good yet?", at the very least they'll walk away with one of my cards in hand. I want to make sure that they remember me and I'm the one they call if they really are interested in finding out what might be hiding in their yard or if they ever lose something
Another benefit of having a card to give out comes when you get a "no" when asking permission. Depending on the vibe I get from the person, I'll still give them a card and say something like "here's my card just in case you lose something of value or you change your mind". Without a card, a "no" is (somewhat) permanent once they close the door. If they change their mind, or lose something, they have no way to contact you. But left with a card, I'm likely the first person they'll think of, and I can be readily reached.
Sure, the vast majority of my cards will end up either thrown away or in the bottom of someone's junk drawer. But if only a couple of those cards results in a new permission, then they easily paid for themselves!
Love this idea, what a great way to get permissions. I'm curious if you would be willing to share what your card looks like. I'm looking to make my own.
I'll pm a couple pics of the card I use in a few minutes, RRF.
