Raul scored the goal on February 19 in a 4-0 win over Bundesliga rivals Wolfsburg.
"I'm experiencing wonderful times in the Bundesliga and I'm very proud of the affection shown to me by the German fans," said Raul, who has scored 33 goals since joining Schalke in the summer of 2010.
"It's obviously a wonderful gesture to German football as a whole," said Manuel Neukirchner, director of the museum which opens in 2014.
"Obviously these objects will be given a place of honour."
The 34-year-old Spaniard scored 323 goals for Real Madrid, where he started his professional career in 1994, and won the Champions League three times.
He added another 44 with the Spanish national team and 33 with Gelsenkirchen.
