I mananaged to fix this by having the code check the displayname, item short name, AND the category

private void OnCollectiblePickup(Item item, BasePlayer player)
        {
            float modifier;
            if (PickupResourceModifiers.TryGetValue(item.info.displayName.english, out modifier))
            {
                item.amount = (int)(item.amount * modifier);
            }
            else if (PickupResourceModifiers.TryGetValue(item.info.shortname, out modifier))
            {
                item.amount = (int)(item.amount * modifier);
            }
            else if (PickupResourceModifiers.TryGetValue(item.info.category.ToString(), out modifier))
            {
                item.amount = (int)(item.amount * modifier);
            }
            else if (PickupResourceModifiers.TryGetValue("*", out modifier))
            {
                item.amount = (int)(item.amount * modifier);
            }
        }​
