Last year the breakdown was 50/50 (300+ total), candy bars/coins, this year 71/29 (229 total). It was surprising to me as the coins were better, maybe each worth 40 to 50 candy bars (except the small bronzes).

32 Severan (or therabouts) provincial bronzes
29 Imperial denarii
5 Constantine (or therabouts) small bronzes
66 total

We pushed the coins more last year "1600 year old Roman coin ..." as opposed to "Roman coin", I was more neutral presenting the choice. Next year I'll be more informative about the coins and have a handout in case anyone wants it.

Some of the comments were priceless, however, for example -

One father: "I bet there is no Tiberius in there" (Vespasian/Domitian/Marcus Aurelias/others - many of them women)

One mother: "This should be an experiment ... but of course that's what you are doing"

Two separate sets of teenagers to one another when walking away: "Awesome"

Another teenager: "I got the coin last year" (she took the candy this time)
