Zero to Sixty in 7.0 Caches Challenge Mystery Cache

You've heard that description, "0 to 60 in ..." so many seconds? That is a way to brag about your car's performance, in how quickly it can accelerate from 0 to 60 mph. Outside the United States and United Kingdom, the standard is 0 to 100 km/hour.

This challenge is likely to take longer than a few seconds. Your goal is to find seven caches that contain the numbers 0, 10, 20, 30, 40, 50, and 60. Each number cannot be part of another number, nor can they be spelled out; e.g. 010, 100 or Zero do not qualify for 0.

Past finds do count. Only one cache from a series is allowed however. When logging your finds, please use the format in the completed list below. If you wish to list the 100 km/hr standard, feel free but it is not required for this challenge.
