How is the if statement getting the nil value from the first part in parenthesis? (SOLVED)

Hey guys, As you can probably tell from the title, this following code keeps telling me I'm comparing a nil value to a number.

Here is the code:

local hs = game:GetService("HttpService")
local got_table = hs:GetAsync("https://search.rprxy.xyz/catalog/json?CatalogContext=1&Subcategory=2&SortAggregation=5&PageNumber=1&LegendExpanded=true&Category=2", true)
local json_table = hs:JSONDecode(got_table)
local dic_values = 0;
local common = {} -- 0 and 2,500
local uncommon = {} -- 2500 and 9,000
local rare = {} -- 9000 and 75,000
local legendary = {} -- 75000 and 500,000
local ultra_rare = {} -- 500,000 and 999,999,999,999


for i = 1, 44 do
    print("Page #"..i..":")
    repeat

    for index,value in next, json_table do -- Counts the amount of values in the dictionary.
        dic_values = dic_values + 1;
    end

    got_table = hs:GetAsync("https://search.rprxy.xyz/catalog/json?CatalogContext=1&Subcategory=2&SortAggregation=5&PageNumber=" .. i .. "&LegendExpanded=true&Category=2", true)
    json_table = hs:JSONDecode(got_table)
    until dic_values > 0

    for index, value in next, json_table do -- Prints all the values inside dictionary.
        if ((tonumber(value.BestPrice) or tonumber(value.Price)) >= 0 and (tonumber(value.BestPrice) or tonumber(value.Price)) <= 2500) then
        print(tonumber(value.BestPrice))
    end
    end
end

print("Values are done!")

Apparently, the first part of the if statement on line #25, which is:

if ((tonumber(value.BestPrice) or tonumber(value.Price))

is giving me a nil value. I have no clue as to how that is happening because, I am using ternary and an object in catalog can't be missing both a BestPrice and a Price. So, if the first value is nil, it should just go to the next value.

Any help is appreciated and thank you, once again.
