Cash
The official description says the code SLOP is for some cash. It does not print an amount. Publishers report 900 Cash for SLOP and other Cash amounts on codes such as 3KCCU. Those reports were not redeemed for this page. Read the summon or merchant price in the currency that button shows.
Gems
Gem amounts show up in code reports: 100 on MINIUPDATE, 200 on 3KSERVERMEMBERS, 250 on 3KCCU, and 250 on 1MVISITS! when that code is treated as active. None of those reports set the price of a summon.
Raid Crystals and Stars
A September 21 raid guide reports Raid Crystals for the Raid Merchant. Stars appear in older expired code reports for SPACE and ALIEN, listed as 250 Stars each. Earning rates and any exchange between these wallets were not verified. Compare farms with the currency the result screen pays, over several runs, not with a single quoted number.
Slopbux, Suns, and Sheckles
SORRYABOUTSLOPBUX is reported as 25 Slopbux by lists that still call it active, and as expired by other lists. DATA WIPE 1 and DATA WIPE 2 swap 500 Suns and 500 Sheckles depending on the publisher. No spending route is inferred from those names.
Trade value
A unit at 1,000 community value is not a 1,000 Cash unit and not a 1,000 Robux unit. Price trades on one dated range. Pay merchants with the wallet the game displays.
