I gathered sales of Deepsea Rave Taunt: Conga from different sites, such as Marketplace.tf, Backpack.tf and the Steam Community Market (SCM), so I grouped them by channels below.

Marketplace.tf sales

I'm considering the Mann Co. Supply Crate Key Median price of the same day the unusual was sold at Marketplace.tf. You can check TF2 key Sales Stats HERE.

Sale 1

07/29/23. I bought it for 40 USD, the key price of that day in Marketplace was 1.95 USD, 40/1.95 ~ 20.5 keys. Proof of my purchase (screenshot)

Sale 2

08/20/23. 1 sold for 59.99, the key price of that day in Marketplace was 2 USD, 59.99/2 ~ 30 keys. Deepsea Rave Taunt: Conga Sales Stats

Sale 3

08/26/23. 1 sold for 59.99, the key price of that day in Marketplace was 2 USD, 59.99/2 ~ 30 keys. Deepsea Rave Taunt: Conga Sales Stats

Backpack.tf sales

Sale 4

08/06/23. 1 sold for 30 keys pure. Proof (screenshots)

Sale 5

08/17/23. 1 sold for 18 keys pure. Proof (screenshots)

Note: the seller was from Poland, so the screenshots he shared me are not in english. It seems "głębinowa potáncówka" means Deepsea Rave.

SCM sales

I'm considering the Mann Co. Supply Crate Key average price of the same date and hour the unusual was sold at SCM. You can check TF2 key listings HERE.

Note: I'm from Chile so my currency is Chilean pesos (CLP), if the sold price in CLP it's not the same, it's because currency exchange fluctuates everyday.

Sale 6

08/04/23 2PM. 1 sold for 55 euro (seller's currency) ~ 59.01 USD, key price was 2.25 USD, 59.01/2.25 ~ 26.2 keys. Proof (screenshots)

Sale 7

08/10/23 2PM. 1 sold for 73.35 USD (seller's currency), key price was 2.23 USD, 73.35/2.23 ~ 32.9 keys. Proof (screenshots)

Note: 08/10/23 2PM there were 2 sales of Unusual Taunt: Conga, 1 of those sales was this unusual effect (Deepsea Rave), the other unknown. Since there were 2 sales during the same hour, the graph is only taking the average price.

Sale 8

08/13/23 12AM. 1 sold for 55 USD (seller's currency), key price was 2.20 USD, 55/2.20 = 25 keys. Proof (screenshots)

Sale 9*

08/27/23 5PM. 1 sold for 46 USD (seller's currency), key price was 2.20 USD, 46/2.20 = 20.9 keys. Proof (screenshots)

Note: I'm assuming the seller changed it's original price, from 40.2 USD to 46 USD, can't tell since it disappeared from the SCM in less than 1 day.

Sale 10

08/27/23 7PM. 1 sold for 60 euro (seller's currency) ~ 64.61 USD, key price was 2.19 USD, 64.61/2.19 = 29.5 keys. Proof (screenshots)

New price suggestion

The key prices of the 10 sales from above in ascending order are:

- 18

- 20.5

- 20.9

- 25

- 26.2

- 29.5

- 30

- 30

- 30

- 32.9

I'm considering 18 and 32.9 keys as outliers, so for this new price suggestion I'll take a low value of 21 key and a high value of 30 keys.

Let me know what you think.
