OK parents, which one of you is leaving real folding money under your kid's pillow when the Tooth Fairy comes to call?

A new study from Visa says the average bounty for a missing tooth nationwide has risen in recent years to $3.70 (more in the Northeast โ€” shocker โ€” less in the Midwest).
Why? At least some parents don't want their kids to be the ones at the playground who received the lowest amount, and somewhere some parent left a twenty to ease the pain. Whose feelings and reputations this is meant to protect is up for debate.
Way back when, if I had a stubborn loose baby tooth, the best I could hope for was a Milky Way bar to dislodge the thing (thanks, Mom) and maybe a fancy silver dollar under the pillow (you too, Dad).
How about you?
