There's a book (possibly series) that I read as a youngster (probably about 29 years ago) that I cannot remember the title. Every so often it pops into my head and drives me crazy because I cannot remember its name or author. It was a story of 4 kids who, inspired by seeing the movie "Ivanhoe" combined their toys to make castles and use their dolls/action figures to create/recreate the Ivanhoe story. Each night they wake up in this created world. They find that by moving the toys around the following day they can affect the outcome of next's nights adventure.
A fuzzy part of me thinks it has something to do with a magic coin they find. But I am not sure if that was part of that book or the next in the series.
Can anyone help me with this mystery? I truely do not know the age of the book since I got it from the local library.
