Best JOB seems to be 8/5 at dollar or higher denominations.

JoB 7/5 on the first floor at the quarter level and worse at the nickel level

Horseshoe Baltimore has changed their coin-in policy. The second floor of the facility is $45 a point for VP. This floor mainly has the $1,$2,$5,$10 and up VP. The first floor is still $10 to a point but the VP games generally have worse pay tables.

Horseshoe Baltimore opened August 26, 2014.

Just got home from Horseshoe in Baltimore. I had time for a quick look around. The casino occupies two floors. Place was very busy. Did not see any playable VP under $1. I did find two uprights that both had 9/6 Jacks and 9/6 Double Double Bonus on the them. These are $1, $2 and $5 multi-denomination. They are located on the second level and to the right at the top of the escalator. They are in a carousel of 8 uprights and the two that are full-pay are facing the exit to the outdoor smoking area. And by the way, they actually have slots machines outside for the smokers to play while they inhale. I think these two full pay machines are either there by mistake, or are just there for the first few weeks of the grand opening. I've seen this trick before. Time will tell, dah. Don't know how much in per point.
