You are creating 1000 pickup in same location for all players
Use streamer so you can create 1 pickup for each player

Код:

CreateDynamicPickup(modelid, type, Float:x, Float:y, Float:z, worldid = -1, interiorid = -1, playerid = -1, Float:streamdistance = 100.0);

PHP код:

for(new i; i < MAX_PLAYERS; ++i)
    {
        HorseShoe[i] = CreateDynamicPickup(954, 2, 985.0377, 2562.6399, 11.0507, 0, 0, i);
    } 


Also you need to destroy the pickup after its picked
