Seeing each donation that led to adding up to that amount may help.

Yes, because it would show how many people donated. Number of people = power, at least in our brains.

The difference between one person donating 100 000, or one person donating 50 000 and ten people donating 5 000 is that in the latter case, your team has eleven people. It is the same amount of money, but emotionally it feels better. Probably it has other advantages (such as smaller dependence on whims of a single person), but maybe I am just rationalizing here.
