The absolute low appears to be ~2e-5, and the (very temporary) high after that is 6e-3, which is a ~300x rally. However, the 6e-3 high was very temporary, with 4e-4 being the more durable high, with current prices running ~1-2e-4.

...I'm finding it easier to refer to the prices here in scientific notation, and to look at the price graph in log scale. That gives you an idea of how far the price has gone.
