In April, Kean was subjected to racist abuse from the stands in a 2-0 Serie A win at Cagliari.
When he scored the second goal late on he stood facing the crowd with his arms spread, something he later posted an image of on Instagram, with the caption: "The best way to respond to racism #notoracism".
A JustGiving page was created on Sunday which said it was to fund a banner for Goodison Park that will "show Kean we are a family at Everton and united against racism."
On Tuesday afternoon it had over 200 supporters, with the the total raised more than £2,500 - the target had been £1,000.
When asked about that at a press conference on Tuesday, Kean said: "It is beautiful. Racism is horrendous and we have to fight hard against racism. I'm going to repay the fans for all they do for me.''
