Yoshi's Island 4-5 Red Coins Value

I have played through this game so many times, and yet...I'm always missing one red coin in 1-7, preventing me from earning 100 points all across the board. I have scavenged every other level and managed a perfect 100, but that 1-7 just gets me every time.
Does anyone else fondly remember this game? Did you have the same trouble in Touch Fuzzy, Get Dizzy?
Incidentally, while I played this game as a child, my original copy was lost in a house fire. When I finally replaced it, the price was FORTY DOLLARS. It is, to date, the most I have paid for a Nintendo game and it was totally worth it!
