I too had a currency this morning in the infamous upper center location.
For my screen, at my preferred zoom, this is almost (but not completely) hidden from view; a little tip of the currency just barely sticks out. Normally, I either switch from city to map to city to see if I continue to get the "you have currency" message, or I zoom in, zoom out until I just get the notification bars so the currency is no longer under the interface.
Today, I tried clicking on the currency, and found that there is a magic sweet spot which, while not visually a part of the currency icon, will still let me collect the currency.
Soooo, I am able to see it without changing my zoom, and I am able to collect it without changing my zoom. I guess.
I don't like it.
