If you put the coins in a model/folder and call them 1, 2, 3 etc., you can do something like this in a script inside that model/folder (assuming you have a leaderstat called Coins):
for _,v in pairs(script.Parent:GetChildren()) do if v:IsA("BasePart") then v.Touched:Connect(function(hit) if not script.Parent:FindFirstChild(tonumber(v.Name)-1) then local plr = game.Players:GetPlayerFromCharacter(hit.Parent) if plr and plr:FindFirstChild("leaderstats") then plr.leaderstats.Coins.Value = plr.leaderstats.Coins.Value + 1 end v:Destroy() end end) end end
