Twice the number of stamps given by Mike is 17 stamps * 2 = <<17*2=34>>34 stamps
Harry therefore gave Tom 10 stamps + 34 stamps = <<10+34=44>>44 stamps
Combining both gifts gives a gift total of 44 stamps + 17 stamps = <<44+17=61>>61 stamps
The total number of stamps in Tom’s collection is now 3000 stamps + 61 stamps = <<3000+61=3061>>3061 stamps
