	A '''coin limit''' is the maximum number of coins that can be collected or saved in a given area. Some courses allow infinite coins to be collected. However, in the NTSC (American) version, the coin counter is programmed to stay at the maximum of 999.

	Separately, there is an unintentional coin limit involving the saved coin score. This value overflows and is set to 0 if the number of coins Mario collected in the course is a multiple of 256. (Not within the course, but when recording the saved coin score after Mario exits the course.) Thus, the easiest way to obtain the highest possible saved coin score in a level is to simply collect 255 coins. 511 and 767 also produce a saved coin score of 255, but collecting more than 255 coins is not as efficient as collecting a star when 255 coins have been collected. 1,023, 1,279, etc. also save as 255, but these coin scores cannot be obtained in the NTSC version.
