Depends on the intentions... are you a farmer bartering your crops for another farmers meat; or are you knowingly circumventing laws.
This is similar to the way Pachinko parlors work in Japan and Taiwan - you collect a ball from the machine when you win, and with a certain amount of balls you can receive various token prizes. This prize can then be redeemed around the corner at a different location for cash. Cash was exchanged - there were just middlemen involved - but it still comes down to gambling.
If you are intending to replace currency with something else not produced by the government, then you are not bartering, you are introducing private currency and that is illegal.
