This glitch works by eating a bob-omb as you jump on a shell, so that Yoshi's tongue gets stuck out. Dismounting the shell and moving will eat the bob-omb and give you a coin, but then when the bob-omb respawns it will still have its coin. This only works with bob-ombs because they are the only enemy that naturally respawns, can be eaten, can't be made into an egg, and gives you a coin.
This glitch can be used to gain one additional coin in Bob-Omb Battlefield, making 230 coins the new maximum. 229 has been the maximum since 2005! cyberscore.me.uk/chart/12812
I don't think this glitch can be used to improve the coin scores of any other courses, but I could be wrong.
A glitch similar to this can also be used to dupe a pokey's coin: youtu.be/BaCGVbOpo40
Update 1: goombas can be used instead of a shell on certain game versions, making 255 coins possible: youtube.com/watch?v=pMhRNbr_2A0
Update 2: there's an alternate, easier method of bob-omb coin duplication that uses a power flower, making 255 coins possible non-TAS: youtube.com/watch?v=B9CoGKLpl8A

In this video I collect 145 coins in The Secret of Battle Fort. This is the maximum amount of coins possible.
Previously, 97 coins was the thought to be the maximum possible, and had stood as the record since 2009 (http://cyberscore.me.uk/chart/54441). That chart was only added in 2009 though, and 97 will have been the record since the games release as there are no tricks or anything. Then on 27/08/16, I discovered red block coin duplication (https://twitter.com/Really_Tall/status/769525511240478720, https://twitter.com/Really_Tall/status/769531823420473344). This works by destroying a block with a punch, kick, ground pound, etc, on the same frame its blown up by a bob-omb. The trick also works if two bob-ombs blow up a block on the same frame, but that isnt useful in Battle Fort. There are 19 blocks each containing 3 coins in Battle Fort, and the glitch gets you an extra 3 coins from each of them. However 3 of the blocks are too far away for bob-ombs to reach them. So thats 16 blocks, so 48 extra coins, bringing the total from 97 to 145.
Most of the video should be self-explanatory: I collect the coins and use the duplication glitch on the 16 blocks its possible on. There are 3 bob-ombs in the course and they each respawn infinitely.
If the bob-ombs fuses lasted longer an additional 9 coins would be obtainable, bringing the total up to 154. Being able to enter Battle Fort as Yoshi would previously have increased the coin total by turning the goombas into eggs and doing some combos, but now with the duplication glitch Yoshi wouldnt even be close to improving it, since he cant be used for the glitch.
This glitch can be done on any version, so 145 is the max on all versions.
Getting 145 coins will probably never be done in real-time, as each duplication is frame-prefect (at 30fps) and there are 16 of them. However the trick is possible, and with only 1 attempt at the stage I managed to get 100 coins on console. Ill try to improve this more and see what I can get.")
