What are these droppings? I discovered them yesterday in guest bedroom, on the sheets, under the pillows. This room is not used frequently, but I do keep it clean and sheets washed. Thank you for your help.

Those are either very small mouse droppings - likely house mice (Mus musculus), or roach droppings. The penny is helpful and the shape suggests mouse droppings, but mouse droppings are usually about 1/4" and these look smaller than that. If you have a magnifying glass, look on the surface for distinct ridges - Ridges= roach, otherwise, house mouse.
